Check Digit Verification of cas no

The CAS Registry Mumber 450401-12-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,5,0,4,0 and 1 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 450401-12:
(8*4)+(7*5)+(6*0)+(5*4)+(4*0)+(3*1)+(2*1)+(1*2)=94
94 % 10 = 4
So 450401-12-4 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
