Check Digit Verification of cas no

The CAS Registry Mumber 474975-41-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,4,9,7 and 5 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 474975-41:
(8*4)+(7*7)+(6*4)+(5*9)+(4*7)+(3*5)+(2*4)+(1*1)=202
202 % 10 = 2
So 474975-41-2 is a valid CAS Registry Number.

New aspects on the selective synthesis of 7-arylpyrido[2,3-d]pyrimidines

Quiroga, Jairo,Insuasty, Henry,Insuasty, Braulio,Abonía, Rodrigo,Cobo, Justo,Sánchez, Adolfo,Nogueras, Manuel

, p. 4873 - 4877 (2002)

Pyrido[2,3-d]pyrimidines have been synthesized via a selective cyclocondensation reaction between 6-aminopyrimidines 1 and the Mannich bases, propiophenone hydrochlorides 2. Intermediates for this reaction, such as the Michael addition adduct and the further hydrated pyrido[2,3-d]pyrimidine were isolated to prove the postulated mechanism. NMR analysis of bidimensional experiments allowed to determine unambiguously the process to obtain 7-arylpyrido[2,3-d]pyrimidines.
