CAS Number of Dimethylthiocarbamoyl chloride is 16420-13-6

CAS Registry Number or CAS Number, CAS Rn, CAS #, is a unique numeric identification Number for a substance (compound, polymer material, Biological sequences, mixture or alloy).

The Chemical Abstracts Service (CAS), an organization of the American Chemical Society, is responsible for assigning a CAS number to each substance that appears in the literature. The aim is to avoid the hassle of having multiple names for chemicals and make it easier to search databases. Almost all chemical databases today allow search by CAS number.

A CAS number is divided into three parts with a hyphen (-). The first part contains two to seven digits, the second part contains two digits, and the third part contains one digit as the verification code. 

CAS numbers are listed in ascending order and have no inherent meaning. The verification code is calculated as follows: Multiply the last digit of the CAS sequence number (the first and second digits) by 1, multiply the last digit by 2, and so on. Then add up all the products, divide the sum by 10, and the rest is the verification code of the third part. For example, if the first two parts of the CAS number of H2O are 7732-18, then its checksum code = (8×1 + 1×2 + 2×3 + 3×4 + 7×5 + 7×6) mod 10 = 105 mod 10 = 5 (mod is the remainder operator), So CAS for water is 7732-18-5.

The CAS No. of Dimethylthiocarbamoyl chloride is 16420-13-6. Dimethylthiocarbamoyl chloride is also named as Carbamoyl chloride, dimethylthio-; Dimethylcarbamothioic chloride; dimethyl-carbamothioicchlorid; Dimethylthiocarbamyl chloride; N,N-Dimethylthiocarbamyl chloride; N,N-DIMETHYLTHIOCARBAMOYL CHLORIDE; N,N-DIMETHYLCARBAMOTHIOIC CHLORIDE; DIMETHYLTHIOCARBAMOYL CHLORIDE. It is light yellow to yellow crystal and is used as medical intermedaite.
