CAS REGISTRY, the global standard for chemical research, approaches 50 millionth registration milestone

Washington, DC (August 16, 2009) - CAS, a division of the American Chemical Society, announced today that it is on track to register the 50 millionth unique chemical substance on September 7.  The CAS REGISTRYSM is the most comprehensive and high-quality compendium of publicly disclosed chemical information.  This milestone came quickly, since it was only 9 months ago that CAS registered its 40 millionth substance.  In contrast, it took 33 years for CAS to register the 10 millionth compound in 1990.

"The pace of discovery in molecular science is quickening," said Dr. Matthew Toussant, Senior Vice President of Editorial Operations at CAS.  "We are finding that the predominant source of new chemical substances is global patent literature."

REGISTRY is the only integrated comprehensive source of chemical information from a full range of patent and journal literature that is curated and quality controlled by scientists working around the world.  For more than 100 years, CAS scientists and colleagues in several nations have meticulously analyzed and indexed publicly disclosed global scientific information to build up the unique REGISTRY resource that provides not only chemical names, the unique CAS Registry Number, and vital literature references but also ancillary information such as experimental and predicted property data (boiling and melting points, etc.), commercial availability, preparation details, spectra, and regulatory information from international sources.

CAS scientists follow rigorous criteria that maintain the famously high quality and reliability of information in its REGISTRY.  Scientists identify reputable sources and use consistent analysis before registering a substance.

"The growth of the CAS REGISTRY is all the more remarkable as CAS rigorously maintains long-trusted standards for registration of substances," says Christine McCue, CAS Vice President of Marketing.  McCue added, "This is why the CAS REGISTRY is the database of record for chemical searching by patent offices around the world as well as being what many call 'the gold standard' for chemical research everywhere."

REGISTRY is available to scientists through CAS' award-winning product, SciFinder, and its STN family of products.  With these advanced search and analysis technologies, CAS helps scientists find reliable information that is vital to their research process.
