Check Digit Verification of cas no

The CAS Registry Mumber 138253-32-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,2,5 and 3 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 138253-32:
(8*1)+(7*3)+(6*8)+(5*2)+(4*5)+(3*3)+(2*3)+(1*2)=124
124 % 10 = 4
So 138253-32-4 is a valid CAS Registry Number.

A porphyrin rigidly linked to one or two terpyridine chelates used as assembling subunits

Collin,Heitz,Sauvage

, p. 5977 - 5980 (1991)

The '2+2' condensation of (3,3'-diethyl-4,4'-dimethyl-2,2'-dipyrrolyl) methane with an aromatic aldehyde bearing a 2,2',6',2''-terpyridine (terpy) ligand leads after oxidation of the intermediate porphyrinogen to a porphyrin bearing two terpy chelates dis
