Check Digit Verification of cas no

The CAS Registry Mumber 255367-21-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,5,3,6 and 7 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 255367-21:
(8*2)+(7*5)+(6*5)+(5*3)+(4*6)+(3*7)+(2*2)+(1*1)=146
146 % 10 = 6
So 255367-21-6 is a valid CAS Registry Number.

Novel synthesis of macrocyclic amine-thiophenolate ligands: X-ray crystal structure of a Ni4 complex of an N8S4 ligand

Kersting, Berthold,Steinfeld, Gunther,Fritz, Thorsten,Hausmann, Julia

, p. 2167 - 2172 (1999)

A novel route to macrocyclic amine-thiophenolate ligands is described. The new, air-stable thiophenolate precursor 1,2-bis(4-tert-butyl-2,6- diformyl-phenylsulfanyl) ethane (4) is readily condensed with two equivalents of 1,2-ethanediamine or 1,3-propaned
