CAS Registry Number is a unique numerical identifier assigned to a specific chemical substance or compound by the Chemical Abstracts Service (CAS). It is an essential tool in the field of chemistry as it serves as a universal means of identification for chemical substances worldwide.
The CAS Registry Number consists of a series of numeric digits and is specific to a particular substance, regardless of its name or synonyms. It is used to ensure accuracy and avoid confusion when different compounds share similar or even identical names. As a result, the CAS Registry Number provides a reliable means of searching and referencing chemical substances, facilitating their identification and retrieval.
CAS, the organization responsible for maintaining the registry, systematically assigns the numbers based on the order of registration. Each number is unique and signifies a particular chemical entity. The registry is continuously updated and expanded as new chemical substances are discovered or synthesized.
Researchers, scientists, and professionals in various fields rely on CAS Registry Numbers to access vital information about chemical substances. These numbers are widely used in scientific literature, patents, regulatory documents, databases, and chemical catalogs. They play a crucial role in promoting accurate communication and effective data exchange within the scientific community.
In summary, the CAS Registry Number is a globally recognized and standardized numerical identifier assigned to chemical substances by CAS. It facilitates the unique and unambiguous identification of substances, enabling efficient retrieval and referencing of chemical information.
