Check Digit Verification of cas no

The CAS Registry Mumber 1253374-15-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,3,3,7 and 4 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1253374-15:
(9*1)+(8*2)+(7*5)+(6*3)+(5*3)+(4*7)+(3*4)+(2*1)+(1*5)=140
140 % 10 = 0
So 1253374-15-0 is a valid CAS Registry Number.

O-Aminothiophenol in reactions with carbonyl compounds and isocyanides: A word of caution

Tsirulnikov, Sergey,Dmitriev, Dmitry,Krasavin, Mikhail

, p. 1935 - 1938 (2010)

The reaction of o-aminothiophenol with carbonyl compounds and t-BuNC was revisited and shown to provide 1-[1,3-benzothiazol-3(2H)-yl]methanimines (not described hitherto) and not the earlier reported 4H-benzo[1,4]thiazine. To isolate the latter using this reaction a due amount of caution and structure scrutiny is warranted. The basis for assignment of the products to both structural classes is provided.
