Check Digit Verification of cas no

The CAS Registry Mumber 50372-92-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,3,7 and 2 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 50372-92:
(7*5)+(6*0)+(5*3)+(4*7)+(3*2)+(2*9)+(1*2)=104
104 % 10 = 4
So 50372-92-4 is a valid CAS Registry Number.

Synthesis, ligand binding, QSAR, and CoMFA study of 3β-(p-substituted phenyl)tropane-2β-carboxylic acid methyl esters

Carroll,Gao,Rahman,Abraham,Parham,Lewin,Boja,Kuhar

, p. 2719 - 2725 (2007/10/02)

A series of 3β-(p-substituted phenyl)tropane-2β-carboxylic acid methyl esters (2) were synthesized and found to possess high affinity for the cocaine binding site in rat striatum. The p-chloro (2c) and p-iodo (2n) compounds, which were the most potent analogues prepared, were found to be 85 and 78 times more potent than (-)-cocaine. The p-bromo (2m) and p-methyl (2d) were also 56 and 60 times more potent than cocaine. QSAR and CoMFA studies were conducted to correlate binding affinity of the cocaine analogues with their structural features. Whereas the QSAR study gave relatively low correlations, the CoMFA study gave a correlation with high predictive value.
