Check Digit Verification of cas no

The CAS Registry Mumber 1578244-28-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,7,8,2,4 and 4 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1578244-28:
(9*1)+(8*5)+(7*7)+(6*8)+(5*2)+(4*4)+(3*4)+(2*2)+(1*8)=196
196 % 10 = 6
So 1578244-28-6 is a valid CAS Registry Number.

Expanding the scope of fused pyrimidines as kinase inhibitor scaffolds: Synthesis and modification of pyrido[3,4-d]pyrimidines

Innocenti, Paolo,Woodward, Hannah,O'Fee, Lisa,Hoelder, Swen

, p. 893 - 904 (2015/02/19)

Fused pyrimidine cores are privileged kinase scaffolds, yet few examples of the 2-amino-pyrido[3,4-d]pyrimidine chemotype have been disclosed in the context of kinase inhibitor programs. Furthermore, no general synthetic route has been reported to access 2-amino-pyrido[3,4-d]pyrimidine derivatives. Here we report a versatile and efficient chemical approach to this class of molecules. Our strategy involves the concise preparation of 8-chloro-2-(methylthio)pyrido[3,4-d]pyrimidine intermediates and their efficient derivatisation to give novel compounds with potential as kinase inhibitors.
