Check Digit Verification of cas no

The CAS Registry Mumber 71642-80-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,6,4 and 2 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 71642-80:
(7*7)+(6*1)+(5*6)+(4*4)+(3*2)+(2*8)+(1*0)=123
123 % 10 = 3
So 71642-80-3 is a valid CAS Registry Number.

2-Arylacetamides as Versatile Precursors for 3-Aminoisocoumarin and Homophthalimide Derivatives: Palladium-Catalyzed Cascade Double Carbonylation Reactions

Frutos-Pedre?o, Roberto,García-López, José-Antonio

, p. 2692 - 2700 (2016)

The synthesis of biologically relevant homophthalimide and 3-aminoisocoumarin nuclei via palladium-catalyzed carbonylation of 2-(2-iodoaryl)acetamides has been developed. The degree of N-substitution on the starting amide substrate dictates whether C?N or
