What is CAS number? The basic concept
of CAS number
CAS number is called "Chemical Abstracts Service Registry Number", that is, Chemical Abstract Service Registration Number. CAS number is a globally unique identification number composed of numbers and hyphens, which can be used to accurately confirm the identity of compounds and is the "identity card" of compounds in academia and scientific research industry ". The origins of the

CAS number can be traced back to 1907, when a publishing company in the United States began to edit and publish the compound's abstract service. In order to manage and distinguish all compounds, the company decided to assign each compound a unique identification number, and the CAS number was born.

the application of CAS in scientific research

CAS plays a vital role in the field of scientific research. Scientists use CAS numbers to identify, identify and distinguish different compounds. For a study, it is very important to determine the identity and purity of a compound. The CAS number allows researchers to quickly and accurately identify a substance, thereby ensuring the accuracy and validity of experimental results.

In addition, CAS numbers are widely used for literature retrieval and storage. Researchers can use the CAS number to find specific compounds mentioned in the literature, which can help speed up the search and improve the efficiency of the study. The CAS number can also be used for database building and searching to help researchers get the information they want quickly. The importance of the

CAS number
the importance of the
CAS number is that it can help scientists accurately identify and distinguish compounds. The use of CAS numbers can improve the reproducibility and accuracy of experimental results, thereby protecting the health and safety of researchers and the public.

In addition, the use of CAS numbers avoids misunderstanding and confusion. Because the common and common names of some compounds may be very similar and easily confused. However, by using the CAS number, the identity of a compound can be accurately confirmed, thus avoiding misunderstanding.

In conclusion, CAS has a very important role in the field of scientific research. It helps scientists identify compounds, improve experimental accuracy, and avoid misunderstanding and confusion. Therefore, it is very important to understand and use CAS numbers.
