Check Digit Verification of cas no

The CAS Registry Mumber 91768-74-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,7,6 and 8 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 91768-74:
(7*9)+(6*1)+(5*7)+(4*6)+(3*8)+(2*7)+(1*4)=170
170 % 10 = 0
So 91768-74-0 is a valid CAS Registry Number.

Microwave-assisted synthesis of tetrazolyl pyrazole amides

Hu, Jun,Wang, Jikui,Zhou, Taoyu,Xu, Yanhua

, p. 525 - 527 (2011)

A rapid and efficient microwave-assisted synthesis N-(1H-tetrazol-5-yl) derivatives of 3-methyl-1-phenyl-1H-pyrazole- 5-carboxamide is described. These tetrazole pyrazole amides have interesting bacteriocidal, pesticidal, herbicidal and antimicrobial activities. They were identified by IR and 1H NMR elemental analyses. The target compounds were obtained in a shorter reaction time compared to conventional heating methods.
