Check Digit Verification of cas no

The CAS Registry Mumber 1104638-98-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,0,4,6,3 and 8 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1104638-98:
(9*1)+(8*1)+(7*0)+(6*4)+(5*6)+(4*3)+(3*8)+(2*9)+(1*8)=133
133 % 10 = 3
So 1104638-98-3 is a valid CAS Registry Number.

, p. 5752 - 5759 (2009)

Thermal and microwave initiated cyclization of 2,4-disubstituted 6-arylethynylpyrimidine-5-carbaldehydes with tert-butylamine has been studied. A novel high-yielding preparation of 2,4-disubstituted 7-arylpyrido[4,3-d]pyrimidines has been developed. The i

An efficient one-pot synthetic method for 2,4-disubstituted 7-arylpyrido [4,3-d]pyrimidines from 2,4-disubstituted 6-(arylethynyl)pyrimidine-5- carbaldehydes and tert-butylamine

experimental part, p. 2799 - 2802 (2009/05/07)

Unexpected thermal cyclization of 2,4-disubstituted 6-(arylethynyl) pyrimidine-5-carbaldehydes with tert-butylamine proceeded to give 2,4-disubstituted 7-arylpyrido[4,3-d]pyrimidines in good yields in the absence of any catalysts. The intermediate compoun
