Check Digit Verification of cas no

The CAS Registry Mumber 36137-09-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,6,1,3 and 7 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 36137-09:
(7*3)+(6*6)+(5*1)+(4*3)+(3*7)+(2*0)+(1*9)=104
104 % 10 = 4
So 36137-09-4 is a valid CAS Registry Number.

Synthesis of 3-aryl-2-[hydroxy(diaryl)methyl]-4-oxo-3,4-dihydroquinazolines

Shemchuk,Chernykh,Levashov,Sytnik,Shemchuk

experimental part, p. 1687 - 1690 (2011/03/19)

By heating arylamides of N-ethoxalylanthranilic acid in the acetic acid mediun in the presence of triethylamine the corresponding ethyl 3-aryl-4-oxo-3,4-dihydroquinazoline-2-carboxylates were obtained. The latter in the conditions of the Grignard reaction formed 3-aryl-2-[hydroxy-(diaryl)methyl] -4-oxo-3,4-dihydroquinazolines. Pleiades Publishing, Ltd., 2010.
