Check Digit Verification of cas no
The CAS Registry Mumber 1202020-05-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,2,0,2 and 0 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1202020-05:
(9*1)+(8*2)+(7*0)+(6*2)+(5*0)+(4*2)+(3*0)+(2*0)+(1*5)=50
50 % 10 = 0
So 1202020-05-0 is a valid CAS Registry Number.

A new and simple synthesis of sulfonyl ureas from sulfonamides and N-alkyl-1,2,4-dithiazolidine-3,5-diones
Gessner, Richard K.,Chibale, Kelly
, p. 2839 - 2843 (2009)
A new, short, and simple synthetic approach to sulfonyl ureas is reported. The method involves the transformation of readily synthesized N-alkyl-1,2,4-dithiazolidine-3,5-diones by reaction with primary sulfonamides. Sulfonyl ureas were obtained in moderat
