Check Digit Verification of cas no

The CAS Registry Mumber 138572-73-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,5,7 and 2 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 138572-73:
(8*1)+(7*3)+(6*8)+(5*5)+(4*7)+(3*2)+(2*7)+(1*3)=153
153 % 10 = 3
So 138572-73-3 is a valid CAS Registry Number.

Development of high-affinity 5-HT3 receptor antagonists. 1. Initial structure-activity relationship of novel benzamides

Youssefyeh,Campbell,Klein,Airey,Darkes,Powers,Schnapper,Neuenschwander,Fitzpatrick,Pendley,Martin

, p. 895 - 903 (2007/10/02)

This report describes the development of novel benzamides which are orally active, highly potent, specific antagonists of 5-HT3 receptors. Described in this first report are the structure-activity relationships that led to novel structures with improved potency and selectivity. From this series of compounds, (S)-28 was identified and selected for further evaluation as a 5- HT3 receptor antagonist. Compared with 5-HT3 antagonists such as GR 38032F, BRL 43694, and metoclopramide, (S)-28 was most active in (a) inhibiting binding to 5-HT3 receptor binding sites in rat entorhinal cortex with an K(i) value of 0.19 nM and (b) blocking cisplatin-induced emesis in the ferret with an ED50 value determined to be 9 μg/kg po.
