Check Digit Verification of cas no

The CAS Registry Mumber 1616629-11-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,6,6,2 and 9 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1616629-11:
(9*1)+(8*6)+(7*1)+(6*6)+(5*6)+(4*2)+(3*9)+(2*1)+(1*1)=168
168 % 10 = 8
So 1616629-11-8 is a valid CAS Registry Number.

, p. 4571 - 4575 (2014/06/24)

N-Substituted 2-iodobenzamides and enaminones undergo cascade transformations to achieve quinazolinones via a copper-catalyzed Ullmann-type coupling, a Michael addition and a retro-Mannich reaction. A unique stereochemical feature of this domino process was that Z-enaminones reacted without external ligands, whereas E-enaminones required the assistance of ligands. This journal is
