Accelerate Innovation

Accelerate Innovation

What if you could double the size of your research team overnight? CAS will help you harness scientific information to spark creativity and drive efficiencies.

Manage Information

Manage Information

The volume of information today is overwhelming. CAS will help make sure your organization always has access to exactly the right information at the right time.

Increase ROI

Market competition is fierce and your resources are limited. CAS solutions will help you maximize the value of every investment.

Protect Intellectual Property

Protect Intellectual Policy

When managing intellectual property, the last thing you want is surprises. CAS will provide a complete view of the landscape so you can make important decisions with confidence.

Unlock R&D productivity with SciFinderⁿ. Spend more time discovering & less time researching with the most chemistry aware relevance engine in the industry.

Formulus® delivers the world's largest collection of formulations from journals, patents, and product inserts, and includes detailed supplier specifications and regulatory resources.

STN® is the premier single source for searching the world's disclosed scientific and technical research.

The foundation of most scientific research is the detailed description of the experimental and analytical techniques utilized in the lab. Finding these methods and protocols in the literature is an arduous and time consuming effort.

Constantly changing regulations and expanding global markets make it challenging to stay on top of compliance requirements. NCI Global is a single resource for up-to-date regulatory information on hundreds of thousands of chemical compounds regulated worldwide. With coverage of nearly 150 international regulatory inventories and lists, NCI Global makes it easy to search by CAS Registry Numbers®, chemical names, and more.

PatentPak® is an integrated workflow solution designed to radically reduce time spent acquiring and searching through full-text patents to find vital chemistry insights.

As scientists work on solving the problems of today, there is much to be learned from the past. Information gaps in your collection can cause wasted time and missed opportunities. ChemZent makes historical research accessible by providing an essential resource, Chemisches Zentralblatt to anyone researching chemistry.

CHEMCATS is the market-leading index of commercially available chemicals and their worldwide suppliers. Integrated in SciFinder®, CHEMCATS provides verified available quantities, prices and supplier contact information for millions of commercially available chemical products from hundreds of suppliers.

Science IP® searches the world’s scientific and technical literature to discover answers and insight that drive confident business decisions.

J Org Chem article substance framework graph

The Journal of Organic Chemistry article "Recent Changes in the Scaffold Diversity of Organic Chemistry As Seen in the CAS Registry" shows the pace of innovation from a structural perspective is accelerating despite the extensive reuse of a relative small number of scaffolds.

Film Patents

By any measure, global innovation is accelerating at a dizzying pace. R&D spending, global patent applications, venture capital investment volume, and the pace of technology M&A all reflect the increase in activity.

As part of the continued commitment to helping R&D leaders accelerate scientific discovery, CAS announced the launch of a breakthrough retrosynthetic capability in SciFinderⁿ . This computer-aided synthetic design (CASD) solution utilizes AI technology, powered by CAS’s unmatched collection of scientist-curated reaction content and leverages John Wiley and Sons, Inc.’s award-winning ChemPlanner technology to now identify predicted retrosynthetic routes for both known and novel compounds.

CAS has partnered with Scilligence to integrate SciFinderⁿ with Scilligence ELN (Electronic Laboratory Notebook). This integration helps scientists simplify their workflow by allowing easy access to vital research information in SciFinderⁿ while maintaining traceability of their ideas. Structure and reaction searches in SciFinderⁿ can now be initiated directly from Scilligence ELN.

CAS continues its partnership with iChemLabs to optimize the efficiency of chemical structure searching and drawing in SciFinderⁿ using ChemDoodle®. Advanced SciFinderⁿ searches are now immediately accessible to ChemDoodle users to increase workflow efficiency.
