Check Digit Verification of cas no

The CAS Registry Mumber 138354-50-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,3,5 and 4 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 138354-50:
(8*1)+(7*3)+(6*8)+(5*3)+(4*5)+(3*4)+(2*5)+(1*0)=134
134 % 10 = 4
So 138354-50-4 is a valid CAS Registry Number.

Hybrid Cholecystokinin-A Antagonists Based on Molecular Modelling of Lorglumide and L-364,718

A series of novel nonpeptide cholecystokinin-A (CCK-A) antagonists have been synthesized.Designed on the basis of the structural homology between lorgumide and L-364,718, as investigated with molecular modeling, these compounds constitute a link between the N-acylglutamic acid and 3-amino-5-phenyl-1,4-benzodiazepin-2-one derived antagonists.The prepared compounds were tested in vitro as antagonists of the binding of -(+/-)-L-364,718 and -CCK-8(S) to rat pancreas and guinea pig brain membranes, respectively.All compounds proved to be selective for the(peripheral) CCK-A receptor, the most potent analogue, 6, having a Ki value of 90 nM.The structure-activity profile of the series of hybrid compounds relates closest to that of the N-acylglutamic acid derived antagonists.
