Chemical Abstracts Service (CAS)

Chemical Abstracts Service (CAS) is a division of the American Chemical Society that provides a comprehensive database of chemical information. It assigns unique identifiers called CAS Registry Numbers to substances, helping researchers easily find information about specific chemicals. CAS collects and organizes data from scientific literature, patents, and other sources, making it a key resource for chemists and scientists. This database includes information on chemical properties, structures, and reactions, helping to facilitate research, discovery, and innovation in chemistry and related fields.
