Check Digit Verification of cas no

The CAS Registry Mumber 1539304-52-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,3,9,3,0 and 4 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1539304-52:
(9*1)+(8*5)+(7*3)+(6*9)+(5*3)+(4*0)+(3*4)+(2*5)+(1*2)=163
163 % 10 = 3
So 1539304-52-3 is a valid CAS Registry Number.

Synthesis and properties of 172-phenyl-5,10,15,20- tetraazatribenzo[b,g,l]pyrazino[2,3-q]porphyrin-173(17 4H)-one

, p. 1812 - 1818 (2013)

172-Phenyl-5,10,15,20-tetraazatribenzo[b,g,l]pyrazino[2,3-q] porphyrin-173(174H)-one was synthesized for the first time by template cyclotetramerization of 5,7-diphenyl-6H-1,4-diazepine-2,3- dicarbonitrile with phthalonitrile. Its complexation with zinc(II) acetate followed a bimolecular mechanism. Acid-base properties of the resulting zinc complex in benzene-acetic acid were studied, and the stability constant of its monoprotonated (at the meso-nitrogen atom) form was determined.
