Check Digit Verification of cas no

The CAS Registry Mumber 225095-38-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,5,0,9 and 5 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 225095-38:
(8*2)+(7*2)+(6*5)+(5*0)+(4*9)+(3*5)+(2*3)+(1*8)=125
125 % 10 = 5
So 225095-38-5 is a valid CAS Registry Number.

A facile one-pot synthesis of pyrido[2,3-d]pyrimidines and pyrido[2,3- d:6,5-d']dipyrimidines

Youssif, Shaker,El-Bahaie, Said,Nabih, Esam

, p. 112 - 113 (1999)

The reactions of enaminones (6-aminouracils) 1a-c and 4 with cyano olefins 2a-b and 5a-f led to the formation of pyrido[2,3-d]pyrimidines. 3a-f and 6a-f in good yield, while the treatment of 4-amino-2-thiouracil 4 with aromatic aldehydes afforded pyridodipyrimidines 7a-c.
