CAS Number Lookup: A Vital Tool in the Chemical Industry

CAS number lookup is a vital tool in the chemical industry, especially when it comes to the identification, management and use of chemicals.CAS number, or

Chemical Abstracts Service Number, is a unique numerical identifier that identifies a specific chemical substance. This article will explore in detail the definition of a CAS number, its role in the chemical industry, and how to conduct an effective CAS number search.

Definition and Importance of CAS Number

The CAS number is a unique sequence of numbers assigned to each chemical substance by the Chemical Abstracts Service (USA). It consists of three parts: the first two parts are numeric and the last part is a check digit. the CAS number not only identifies a single chemical substance precisely, but also helps to avoid the confusion that can be caused by chemical names. In the chemical industry, thousands of compounds are represented through different naming systems and languages, making the use of CAS numbers the standard way of identifying chemicals worldwide.

CAS Number Lookup in the Chemical Industry

CAS number lookups are widely used in the chemical industry and are an indispensable tool in chemical sourcing and supply chain management. It allows suppliers and buyers to locate and identify the exact chemical substances they need and avoid purchasing errors due to naming inaccuracies, and it also plays an important role in chemical compliance management. Different countries and regions have different chemical regulations, and by searching for the CAS number, companies can quickly confirm whether a chemical meets local regulatory requirements. During the R&D process, researchers can use CAS number lookup to obtain detailed information about a chemical substance, including its structure, use, and physical and chemical properties, to speed up the R&D process.

How to perform a CAS number search

There are many ways to conduct a CAS number search, usually through the official website of the Chemical Abstracts Service (CAS). This platform provides a comprehensive database covering detailed information on chemical substances worldwide. In addition to the official CAS database, there are a number of other third-party platforms that also provide CAS number lookup services. These platforms usually integrate a variety of resources that allow users to access the chemical’s name, molecular formula, molecular weight, physical properties, and other relevant data by entering the CAS number. Sometimes, users can also perform a reverse search by chemical name or structural formula to find the corresponding CAS number.

Summary

CAS number lookups are an integral part of the chemical industry, facilitating the accurate identification, procurement and management of chemical substances.

Whether it is in the procurement of chemicals, compliance management, or in the R&D process, CAS number lookup plays an important role. Through the rational use of CAS number lookup tools, chemical companies can effectively improve work efficiency, reduce risks, and ensure product safety and compliance.

These are the important applications and related operations of CAS number lookup in the chemical industry. Understanding and mastering the use of CAS number lookup is crucial for any professional involved in chemical management.
