Check Digit Verification of cas no

The CAS Registry Mumber 613241-20-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,1,3,2,4 and 1 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 613241-20:
(8*6)+(7*1)+(6*3)+(5*2)+(4*4)+(3*1)+(2*2)+(1*0)=106
106 % 10 = 6
So 613241-20-6 is a valid CAS Registry Number.

C-C bond formation by radical cyclization: Synthesis of pyrimidine-annulated heterocycles

Majumdar,Mukhopadhyay

, p. 920 - 924 (2007/10/03)

A number of pyrimidino[3,2-c]tetrahydroisoquinolin-2,4-diones are synthesized in excellent yields from 1,3-dialkyl-5-(N-2′-bromobenzyl,N-methyl)aminopyrimidine-2,4-diones by intramolecular addition of aryl radical to the uracil ring beating the amino nitrogen atom. Usual aerial oxidation in this type of cyclization with Bu3SnH is not observed in the present instance.
