Check Digit Verification of cas no

The CAS Registry Mumber 500903-41-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,0,9,0 and 3 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 500903-41:
(8*5)+(7*0)+(6*0)+(5*9)+(4*0)+(3*3)+(2*4)+(1*1)=103
103 % 10 = 3
So 500903-41-3 is a valid CAS Registry Number.

A convenient synthesis of 5/7-chloro-4H-1, 4-benzothiazines

Kumar, Gulshan,Gupta, Vandana,Gautam,Gupta

, p. 381 - 384 (2002)

5/7-Chloro-4H-1,4-benzothiazines have been synthesized by the condensation of sustituted 2-amino-3/5-chlorobenzenethiol with compounds containing active methylene group in dimethylsulfoxide which causes oxidative cyclization via enaminoketone intermediate. The IR, NMR and Mass spectra have been also included.
