Check Digit Verification of cas no
The CAS Registry Mumber 69019-03-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,0,1 and 9 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 69019-03:
(7*6)+(6*9)+(5*0)+(4*1)+(3*9)+(2*0)+(1*3)=130
130 % 10 = 0
So 69019-03-0 is a valid CAS Registry Number.

Synthesis of some 2-styrylquinazoline derivatives structurally related to certain chemotherapeutic agents.
Botros,Shaban
, p. 646 - 647 (2007/10/09)
The synthesis of certain 2-styryl-4-arylaminoquinazolines having the general formula 1 is described. 4-Chloro-2-styrylquinazolines were prepared by chlorination of 2-styryl-4-quinazolones in benzene solution using phosphorus oxychloride and an excess of dimethylaniline. Reacting the chlorostyrylquinazolines with certain arylamines afforded 1.
