Check Digit Verification of cas no

The CAS Registry Mumber 1437798-43-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,7,7,9 and 8 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1437798-43:
(9*1)+(8*4)+(7*3)+(6*7)+(5*7)+(4*9)+(3*8)+(2*4)+(1*3)=210
210 % 10 = 0
So 1437798-43-0 is a valid CAS Registry Number.

Ligand-Free Pd-Catalyzed and Copper-Assisted C-H Arylation of Quinazolin-4-ones with Aryl Iodides under Microwave Heating

Laclef, Sylvain,Harari, Marine,Godeau, Julien,Schmitz-Afonso, Isabelle,Bischoff, Laurent,Hoarau, Christophe,Levacher, Vincent,Fruit, Corinne,Besson, Thierry

, p. 1700 - 1703 (2015/04/14)

A microwave-assisted method for the palladium-catalyzed direct arylation of quinazolin-4-one has been developed under copper-assistance. This method is applicable to a wide range of aryl iodides and substituted (2H)-quinazolin-4-ones. This protocol provides a simple and efficient way to synthesize biologically relevant 2-arylquinazolin-4-one backbones.
