Check Digit Verification of cas no
The CAS Registry Mumber 126728-21-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,7,2 and 8 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 126728-21:
(8*1)+(7*2)+(6*6)+(5*7)+(4*2)+(3*8)+(2*2)+(1*1)=130
130 % 10 = 0
So 126728-21-0 is a valid CAS Registry Number.

, p. 209 - 216 (1989)
The synthesis of a series of 19 new compounds, 2-arylamino-4-oxo-3,4-dihydropyridopyrimidines 9, and the results of a study of their potassium-sparing diuretic activity are reported.Compounds 9 were obtained by boiling in dimethylformamide a soluti
