Check Digit Verification of cas no

The CAS Registry Mumber 20153-95-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,1,5 and 3 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 20153-95:
(7*2)+(6*0)+(5*1)+(4*5)+(3*3)+(2*9)+(1*5)=71
71 % 10 = 1
So 20153-95-1 is a valid CAS Registry Number.

Reaction of Diazoalkanes with 4H-3,1-Benzothiazine-4-thiones and Coumarin-2-thione

Latif, N.,Zeid, I.,Asaad, F.

, p. 432 - 434 (2007/10/02)

2-Phenyl-, 2-p-tolyl- and 2-p-anisyl-3,1-benzothiazine-4-thiones (Ia-c) react readily with diazomethane yielding the corresponding cis- (IIa-c) and trans- (IIIa-c) 1,3-dithioles.Coumarin-2-thione behaves in a similar manner.Diphenyl- and p,p'-dimethoxydiphenyl-diazomethanes as well as 9-diazofluorene react with Ia-c to give the episulphides.
