Check Digit Verification of cas no

The CAS Registry Mumber 141857-53-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,8,5 and 7 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 141857-53:
(8*1)+(7*4)+(6*1)+(5*8)+(4*5)+(3*7)+(2*5)+(1*3)=136
136 % 10 = 6
So 141857-53-6 is a valid CAS Registry Number.

Synthesis and antimicrobial activity of structurally flexible heterocycles with the 1,4-thiazine heterosystem

Sharma, Praveen Kumar,Fogla, Ankur,Rathore,Kumar

, p. 1103 - 1111 (2012/04/17)

In this work, 4H-1,4-benzothiazines were synthesized by an efficient synthetic method in a single step involving heterocyclization of substituted 2-aminobenzenethiols with β-ketoester. The structures of the synthesized compounds were confirmed by their analytical and spectral data. The synthesized compounds were evaluated for their antimicrobial activity against bacterial species; E. coli and Bacillus cereus. The synthesized compounds showed significant activity against microorganisms, which can be correlated with the privileged heterocyclic structural scaffolds.
