Check Digit Verification of cas no

The CAS Registry Mumber 957437-79-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,5,7,4,3 and 7 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 957437-79:
(8*9)+(7*5)+(6*7)+(5*4)+(4*3)+(3*7)+(2*7)+(1*9)=225
225 % 10 = 5
So 957437-79-5 is a valid CAS Registry Number.

Synthesis of some new thiosemicarbazide and 1,2,4-triazoles heterocycles bearing thiophene nucleus as a potent antitubercular and antimicrobial agents

Vasoya,Chovatia,Paghdar,Joshi

, p. 709 - 710 (2008/09/20)

The starting compound 2-hydrazino carbonyl-3-chloro-5-phenoxy-benzo(b) thiophene on reaction with different substituted phenyl isothiocyanates to give N-substituted arylthiosemicarbazide derivatives (1a-h). 1,2,4-Triazole derivatives (2a-h) have been prepared by the cyclization of arylthiosemicarbazides (1a-h) with sodium hydroxide. All the compounds were screened for their antitubercular activity against Mycobacterium tuberculosis (H37Rv) and some other microbes.
