The Chemical Abstracts Service (CAS) is a division of the American Chemical Society (ACS) and is a leading source of chemical information. Established in 1907, CAS provides a comprehensive database of chemical substances, reactions, and literature references, which is widely used by researchers, scientists, and professionals in the field of chemistry and related disciplines.
History[edit | edit source]
The Chemical Abstracts Service was founded in 1907 by the American Chemical Society to provide a systematic and comprehensive abstracting service for the chemical literature. The first issue of Chemical Abstracts was published in January 1907, and it has since grown to become a critical resource for chemical information.
CAS Registry[edit | edit source]
One of the most significant contributions of CAS is the CAS Registry, a comprehensive database of chemical substances. Each substance in the registry is assigned a unique identifier known as a CAS Registry Number. This number is widely used as a standard identifier for chemicals in scientific literature and databases.
CAS Databases[edit | edit source]
CAS provides several databases that are essential tools for chemical research:
- CAS REGISTRY: The largest and most comprehensive collection of publicly disclosed chemical substance information.
- CAplus: A database of chemical literature and patents, providing access to millions of references from journals, patents, and other sources.
- CASREACT: A database of chemical reactions, offering detailed information on reaction conditions, yields, and more.
- CHEMCATS: A catalog of commercially available chemicals, linking to suppliers and pricing information.
CAS Products and Services[edit | edit source]
CAS offers a range of products and services designed to support research and development in chemistry and related fields:
- SciFinder: A research discovery tool that provides access to the CAS databases, allowing users to search for chemical substances, reactions, and literature.
- STN: A network of scientific and technical databases, offering advanced search capabilities for chemical and patent information.
- MethodsNow: A resource for analytical and synthetic methods, providing detailed protocols and procedures.
Impact on Research and Industry[edit | edit source]
CAS plays a crucial role in the advancement of chemical research and industry by providing reliable and comprehensive information. Researchers use CAS databases to identify new compounds, understand chemical reactions, and explore the scientific literature. Industries rely on CAS for regulatory compliance, patent research, and product development.
