CAS

CAS curates and publishes scientific information for research and intellectual property work. Its databases cover chemical substances, reactions, scientific literature, patents, formulations, analytical methods and commercial sources, with CAS Registry Numbers used as a reference across industry. Researchers use CAS SciFinder to search substances, plan syntheses and review literature, while patent professionals use the STN IP Protection Suite for prior art, freedom-to-operate and patent monitoring searches. Other tools support biology-focused drug discovery, chemical regulatory compliance and supplier sourcing, and CAS also provides custom data and search services. It serves pharmaceutical, chemical and materials companies, patent offices and universities.
