CAS (Chemical Abstracts Service)

CAS, or Chemical Abstracts Service, is a division of the American Chemical Society that maintains a comprehensive database of chemical information. It assigns unique identifiers called CAS Registry Numbers to individual chemicals, helping scientists and industries accurately identify and differentiate substances. CAS provides detailed data such as chemical structures, properties, and safety information, facilitating research, safety assessments, and product development worldwide. Essentially, CAS acts as an extensive chemical library that ensures precise communication and reliable data across the scientific community.
