Check Digit Verification of cas no

The CAS Registry Mumber 78095-22-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,0,9 and 5 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 78095-22:
(7*7)+(6*8)+(5*0)+(4*9)+(3*5)+(2*2)+(1*2)=154
154 % 10 = 4
So 78095-22-4 is a valid CAS Registry Number.

Dopamine Agonist Properties of N-Alkyl-4-(3,4-dihydroxyphenyl)-1,2,3,4-tetrahydroisoquinolines

Jacob, James N.,Nichols, David E.,Kohli, Jai D.,Glock, Dana

, p. 1013 - 1015 (1981)

A series of homologous N-alkyl-4-(3,4-dihydroxyphenyl)-1,2,3,4-tetrahydroisoquinolines was synthesized and examined for a dopamine-like ability to dilate the renal artery.The N-methyl derivative was equipotent to the 3',4'-dihydroxy derivative of the antidepressant agent nomifensine, indicating that the 8-amino group of the latter is not essential for dopamine-like activity.The N-ethyl homologue was reduced in potency when compared to the N-methyl, and the N-n-propyl, surprisingly, was essentially devoid of activity.This was unexpected in view of the fact that in all series of dopamine-like agents reported to date, N-alkylation, when one of the alkyls was an n-propyl group, either allowed retention or enhancement of potency.
