Check Digit Verification of cas no

The CAS Registry Mumber 217495-91-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,7,4,9 and 5 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 217495-91:
(8*2)+(7*1)+(6*7)+(5*4)+(4*9)+(3*5)+(2*9)+(1*1)=155
155 % 10 = 5
So 217495-91-5 is a valid CAS Registry Number.

, p. 1566 - 1579 (2007/10/03)

A series of compounds structurally related to 2-phenyl-4'-(2,3,4,5- tetrahydro-1H-1,5-benzodiazepine-1-carbonyl)benzanilide was synthesized and demonstrated to have arginine vasopressin (AVP) antagonist activity for both V(1A) and V2 receptors. The introduction of a hydrophilic substituent group into the 5-position of the benzodiazepine ring resulted in an increase in oral availability. Especially, the (3-pyridyl)methyl (31b), the 2-(4- methyl)-1,4-diazepan-1-yl)-2-oxoethyl (32i), and the 2-(4-methylpiperazin-1- yl)ethyl (33g) derivatives exhibited high antagonist activities and high oral availability. Details of the synthesis and pharmacological properties of this series are presented.
