Chemical Abstracts Service

Chemical Abstracts Service (CAS) is a division of the American Chemical Society (ACS) and is considered to be the most comprehensive and authoritative source of chemical information worldwide. CAS provides a wide range of services and products that facilitate the discovery, analysis, and management of chemical substances.

Overview

CAS was established in 1907 and has since become a vital resource for researchers, scientists, and professionals in the field of chemistry. Its primary function is to collect, organize, and disseminate chemical information through various databases and publications.

Databases and Services

CAS maintains several databases that cover a vast array of chemical substances and related information. The most notable database is the CAS Registry, which contains detailed information on more than 180 million organic and inorganic substances. Each substance in the registry is assigned a unique CAS Registry Number, which serves as a universal identifier for that particular chemical.

Another important database provided by CAS is the CASREACT, which contains information on chemical reactions and their associated conditions. This database is particularly useful for researchers studying the synthesis and transformation of chemical compounds.

CAS also offers specialized databases such as CHEMCATS, which provides information on commercially available chemicals, and MARPAT, which focuses on patents related to chemical substances.

In addition to its databases, CAS provides various services to help researchers access and utilize chemical information effectively. One such service is SciFinder, a web-based search tool that allows users to explore the CAS databases and retrieve relevant chemical information. SciFinder offers advanced search capabilities, including structure and substructure searching, making it a valuable resource for chemical research.

Importance and Impact

The Chemical Abstracts Service plays a crucial role in advancing scientific research and innovation in the field of chemistry. By providing comprehensive and reliable chemical information, CAS enables researchers to make informed decisions, design experiments, and develop new chemical compounds.

The unique CAS Registry Number assigned to each chemical substance facilitates accurate identification and tracking of chemicals, ensuring consistency and clarity in scientific communication. This standardized identification system has become an essential tool for researchers, regulatory agencies, and industry professionals.

CAS also contributes to the safety and regulatory compliance of chemical substances. By maintaining databases that include information on hazardous properties, toxicity, and regulatory status, CAS helps researchers and professionals assess the potential risks associated with specific chemicals.
