Check Digit Verification of cas no

The CAS Registry Mumber 287721-05-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,7,7,2 and 1 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 287721-05:
(8*2)+(7*8)+(6*7)+(5*7)+(4*2)+(3*1)+(2*0)+(1*5)=165
165 % 10 = 5
So 287721-05-5 is a valid CAS Registry Number.

Synthesis and binding affinities of 4-diarylaminotropanes, a new class of delta opioid agonists

Boyd, Robert E.,Carson, John R.,Codd, Ellen E.,Gauthier, A. Diane,Neilson, Lou Anne,Zhang, Sui-Po

, p. 1109 - 1111 (2000)

A series of 4-diarylaminotropanes has been prepared. Both endo and exo diastereomeric forms bound to the delta opioid receptor but the endo isomers were more potent and selective versus the μ opioid receptor than the exo isomers. The most potent delta opioid agonist (14) exhibited a delta opioid K(i) of 0.2 nM and was 860-fold selective over mu. (C) 2000 Elsevier Science Ltd. All rights reserved.
