Check Digit Verification of cas no

The CAS Registry Mumber 19655-72-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,6,5 and 5 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 19655-72:
(7*1)+(6*9)+(5*6)+(4*5)+(3*5)+(2*7)+(1*2)=142
142 % 10 = 2

Amidine derivatives of opioids of the formula YN-X-(NH)n-C(=NR)-R' in which YN is a morphine-like opioid radical; X is a direct bond, a substituted or unsubstituted, branched, straight-chained or cyclic alkylene having from 1 to 6 carbon atoms, optionally containing one or two heteroatoms in the alkyl chain, or an optionally substituted, branched or straight-chained alkenylene having from 4 to 10 carbon atoms; R and R' are independently hydrogen, alkyl, substituted alkyl, alkene, substituted alkene, alkyne, substituted alkyne, aryl, substituted aryl, heterocycle, substituted heterocycle or cyano; and n is 0 when X is said direct bond, or n is 1 when X is said alkylene or alkenylene. The compounds are effective in treating pain, and have effect in the peripheral nervous system, with comparably less or no activity in the central nervous system.
