When getting the science wrong isn’t an option, can you trust your AI?
When stakes are highest, you need answers that can be sourced and defended. Most AI tools were built for language, but CAS Newton is built on over 150 years of peer-reviewed scientific literature that is curated by CAS scientists and interconnected across disciplines. Every answer it provides is one you can trust and verify.

From question to discovery
CAS Newton does not just retrieve information. It reasons through it, connects it, and returns answers you can act on immediately.
A trusted scientific foundation
Every answer is grounded in the CAS Content Collection™, curated and refined by CAS scientists. Get conclusions you can stand behind because the evidence behind every output is authoritative, verifiable, and citable.
Science that goes deeper
Complex, multi-part questions become targeted search paths across chemistry, biology, and more. Science-specific capabilities including structure search, functional group reactivity, spectra prediction, and properties prediction surface what a standard search cannot reach.
Complex research that moves faster
Multi-step research workflows run autonomously. Vast reference sets become clear, actionable direction. As findings emerge, hidden relationships and trends surface across the CAS Content Collection™ without requiring you to manually piece results together.
Decisions you can stand behind
Get the evidence to generate hypotheses, validate assumptions, and support competitive analysis and trend identification. Verified scientific evidence sits behind every recommendation, so every decision your organization makes is defensible.
Integrated into your workflow
CAS Newton, everywhere you work
CAS Newton is available within CAS SciFinder® and CAS BioFinder®. CAS will expand access to CAS Newton across additional CAS solutions over time as capabilities evolve.
