Check Digit Verification of cas no
The CAS Registry Mumber 27685-90-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,6,8 and 5 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 27685-90:
(7*2)+(6*7)+(5*6)+(4*8)+(3*5)+(2*9)+(1*0)=151
151 % 10 = 1
So 27685-90-1 is a valid CAS Registry Number.

Benzazoles. 4.* Synthesis and chemical reactions of 6-chlorosulfonylbenzoxazolin-2-ones
Karimova,Dushamov,Kuryazov,Mukhamedov
, p. 90 - 95 (2011)
The corresponding 6-chlorosulfonyl derivatives were synthesized from benzoxazolin-2-one and its 3-methyl derivative by treatment with chlorosulfonic acid. By treatment of the compounds obtained with water and other nucleophilic reagents (aliphatic and heterocyclic amines) 2-oxobenzoxazoline-6-sulfonic acids and a series of their amides were obtained, while reduction with SnCl 2?2H2O gave 6-mercaptobenzoxazolin-2-ones.
