Check Digit Verification of cas no

The CAS Registry Mumber 136003-85-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,0,0 and 3 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 136003-85:
(8*1)+(7*3)+(6*6)+(5*0)+(4*0)+(3*3)+(2*8)+(1*5)=95
95 % 10 = 5
So 136003-85-5 is a valid CAS Registry Number.

Synthesis of bis-porphyrins containing a 2,9-diphenyl-1,10-phenanthroline spacer

Chabdon-Noblat, Sylvie,Sauvage, Jean-Pierre

, p. 5123 - 5132 (1991)

The synthesis of bis-porphyrins disposed in an oblique fashion is described. The tetrapyrrole rings are linked via a 2,9-diphenyl-1,10-phenanthroline spacer. Two routes have been investigated: a step wise procedure and a direct strategy involving a double cyclisation step. From the bis-free base porphyrin, synthesized with an overall yield of 1% from 2,9-di(p-tolyl)-1,10-phenanthroline, an unsymmetrical zinc (II) porphyrin free base system was prepared and isolated in view of excited state energy and electron transfer.
