Check Digit Verification of cas no

The CAS Registry Mumber 1522-21-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,2 and 2 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1522-21:
(6*1)+(5*5)+(4*2)+(3*2)+(2*2)+(1*1)=50
50 % 10 = 0
So 1522-21-0 is a valid CAS Registry Number.

THE CHLORINATION OF KETONES USING TRIMETHYLCHLOROSILANE AND DIMETHYLSULFOXIDE WITH BROMIDE ION CATALYSIS

Fraser, Robert R.,Kong, Fanzuo

, p. 1071 - 1078 (2007/10/02)

Chlorination using trimethylchlorosilane and dimerthylsulfoxide with bromide ion catalysis afforded almost quantitative yields for 1,3-diphenylacetone, benzoylacetone and propiophenone, and acceptable yields for acetophenone, acetylacetone and cyclohexanone.
