Check Digit Verification of cas no

The CAS Registry Mumber 122012-93-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,0,1 and 2 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 122012-93:
(8*1)+(7*2)+(6*2)+(5*0)+(4*1)+(3*2)+(2*9)+(1*3)=65
65 % 10 = 5
So 122012-93-5 is a valid CAS Registry Number.

Efficient α-chlorination of carbonyl containing compounds under basic conditions using methyl chlorosulfate

Silva, Saúl,Maycock, Christopher D.

, p. 1233 - 1238 (2018)

An efficient method for the α-chlorination of ketones under basic conditions is described using methyl chlorosulfate. Its applicability for the chlorination of other functional groups has also been studied and it is equally useful for the synthesis of α-chloroesters and amides. Methyl chlorosulfate is described for the first time as a positive chlorine source. Some aldol reactions which occur during the chlorination of some substrates are also reported.
