Check Digit Verification of cas no

The CAS Registry Mumber 131353-75-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,3,5 and 3 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 131353-75:
(8*1)+(7*3)+(6*1)+(5*3)+(4*5)+(3*3)+(2*7)+(1*5)=98
98 % 10 = 8
So 131353-75-8 is a valid CAS Registry Number.

Synthesis of 5,15-Diaryl-Substituted Porphyrins by Aminomethylation of Bis(4-ethyl-3-methyl-2-pyrryl)phenylmethanes

Hombrecher, Hermann K.,Horter, Gaby

, p. 219 - 227 (2007/10/02)

The synthesis of unsymmetrically diarylsubstituted porphyrins 11a-g (yields 5-19 percent) is described.Aminomethylation of dipyrromethane 6a with Mannich reagent 9 in acetonitrile leads to the intermediate 10, which is directly converted into the porphyri
