Check Digit Verification of cas no

The CAS Registry Mumber 203251-39-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,3,2,5 and 1 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 203251-39:
(8*2)+(7*0)+(6*3)+(5*2)+(4*5)+(3*1)+(2*3)+(1*9)=82
82 % 10 = 2
So 203251-39-2 is a valid CAS Registry Number.

A New Approach for the Synthesis of some 1,4-Benzoxathiin 4,4-Dioxide Derivatives

Fan, Ai-Long,Cao, Song,Zhang, Zheng

, p. 1657 - 1660 (1997)

A series of 1,4-benzoxathiin 4,4-dioxide derivatives have been prepared by a new synthetic route. The reactions of 2-chloro-4-nitrobenzenethiol 1 with 1-aryl-2-chloroethanones 2 in the presence of sodium hydroxide give 1-aryl-2-(2-chloro-4-nitrophenylthio
