Check Digit Verification of cas no

The CAS Registry Mumber 262273-99-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,2,2,7 and 3 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 262273-99:
(8*2)+(7*6)+(6*2)+(5*2)+(4*7)+(3*3)+(2*9)+(1*9)=144
144 % 10 = 4
So 262273-99-4 is a valid CAS Registry Number.

Regioselective reaction of 5,15-disubstituted porphyrins with organolithium reagents - Synthetic access to 5,10,15-trisubstituted porphyrins and directly meso-meso-linked bisporphyrins

Senge, Mathias O.,Feng, Xiangdong

, p. 3615 - 3621 (2008/10/08)

The reaction of organolithium reagents with 5,15-disubstituted porphyrins, followed by hydrolysis of the intermediate anion to give a porphodimethene and oxidation with DDQ allows the facile preparation of 5,10,15-tri-and 5,10,15,20-tetrasubstituted porph
