2157-80-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2157-80-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,5 and 7 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 2157-80:
(6*2)+(5*1)+(4*5)+(3*7)+(2*8)+(1*0)=74
74 % 10 = 4
So 2157-80-4 is a valid CAS Registry Number.

Synthesis of Highly Fluorinated Chloroformates and Their Use as Derivatizing Agents for Hydrophilic Compounds and Drinking-Water-Disinfection by-Products

Vincenti, Marco,Ghiglione, Nicoletta,Valsania, Maria Carmen,Davit, Patrizia,Richardson, Susan D.

, p. 370 - 375 (2007/10/03)

A rapid, safe, and efficient procedure was developed to synthesize, on a small scale, fluorinated chloroformates often required to perform analytical derivatizations. This new family of agents allows straightforward derivatization of highly polar compounds (with multiple hydroxy, carboxy, and amino substituents) in the aqueous phase, compatible with GC and GC/MS analysis. A goal of this work was to develop a derivatization procedure that would enable the detection and identification of highly polar disinfection by-products in drinking water.
