Check Digit Verification of cas no

The CAS Registry Mumber 90030-13-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,0,3 and 0 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 90030-13:
(7*9)+(6*0)+(5*0)+(4*3)+(3*0)+(2*1)+(1*3)=80
80 % 10 = 0
So 90030-13-0 is a valid CAS Registry Number.

Templated synthesis of interlocked macrocyclic ligands, the catenands. Preparation and characterization of the prototypical bis-30 membered ring system

Dietrich-Buchecker, Christiane,Sauvage, Jean-Pierre

, p. 503 - 512 (1990)

We describe here the detailed template synthesis of a copper(I) catenate. Demetallation leads to the corresponding free ligand, a catenand. Both molecules are made of two interlocked 30 membered rings.
