Check Digit Verification of cas no

The CAS Registry Mumber 140652-73-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,6,5 and 2 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 140652-73:
(8*1)+(7*4)+(6*0)+(5*6)+(4*5)+(3*2)+(2*7)+(1*3)=109
109 % 10 = 9
So 140652-73-9 is a valid CAS Registry Number.

Carbazoylations and thiocarbazoylations of 2-thioxo-thiazolidines

Hanefeld,Gosseln

, p. 173 - 175 (1992)

Reactions of thiazolidine-2-thione (1) with carbazic and thiocarbazic acid chlorides 5 lead to S-substitution products 6 which only in case of the carbazoic derivatives can be thermally rearranged to N-carbazoyl derivatives 7. Not rearrangeable heteroarom
