Check Digit Verification of cas no

The CAS Registry Mumber 1189147-45-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,9,1,4 and 7 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1189147-45:
(9*1)+(8*1)+(7*8)+(6*9)+(5*1)+(4*4)+(3*7)+(2*4)+(1*5)=182
182 % 10 = 2
So 1189147-45-2 is a valid CAS Registry Number.

Efficient synthesis of 2-substituted pyrido[3,2-d]pyrimidines involving SNAr and palladium-catalyzed cross-coupling reactions

Tikad, Abdellatif,Routier, Sylvain,Akssira, Mohamed,Leger, Jean-Michel,Jarry, Christian,Guillaumet, Gerald

experimental part, p. 2379 - 2384 (2010/02/27)

The efficient and original synthesis of various 2-substituted pyrido[3,2-d]pyrimidines is reported. Starting from 2,4-dichloropyrido [3,2-d]pyrimidine, a regioselective pallado-dehalogenation led to 2-chloropyrido[3,2-d]pyrimidine, which was used in SNAr and palladium-catalyzed cross-coupling reactions in order to afford highly functionalized products in very good yields.
