Check Digit Verification of cas no

The CAS Registry Mumber 6367-24-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,3,6 and 7 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 6367-24:
(6*6)+(5*3)+(4*6)+(3*7)+(2*2)+(1*4)=104
104 % 10 = 4
So 6367-24-4 is a valid CAS Registry Number.

Simple Spectrophotometric Method for Determination of Carbonyl and Sulfonyl Chlorides

Siewinski, Maciej,Kuropatwa, Marianna,Szewczuk, Apolinary

, p. 2882 - 2884 (2007/10/02)

The method presented is based on the reaction of carbonyl and sulfonyl chlorides with sodium azide in water-acetone solution at room temperature for 10 min; the excess of azide is determined spectrophotometrically after conversion to a red complex with Fe3+.Reactive anhydride can also be determined by this method.The application of the new method was demonstrated for monitoring conversion of sulfonyl chlorides to sulfonyl fluorides and for controlling the acylation of amino compounds with phthaloyl-L-glutamic anhydride.
