Check Digit Verification of cas no

The CAS Registry Mumber 916994-57-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,6,9,9 and 4 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 916994-57:
(8*9)+(7*1)+(6*6)+(5*9)+(4*9)+(3*4)+(2*5)+(1*7)=225
225 % 10 = 5
So 916994-57-5 is a valid CAS Registry Number.

Synthesis of 2-azaindolizines by using an iodine-mediated oxidative desulfurization promoted cyclization of N-2-pyridylmethyl thioamides and an investigation of their photophysical properties

Shibahara, Fumitoshi,Kitagawa, Asumi,Yamaguchi, Eiji,Murai, Toshiaki

, p. 5621 - 5624 (2006)

Iodine-mediated, oxidative desulfurization promoted cyclization of N-2-pyridylmethyl thioamides serves as an efficient and versatile method for the preparation of 2-azaindolizines (imidazo[1,5-a]pyridines) and rare 2-azaindolizine sulfur-bridged dimers. T
