Check Digit Verification of cas no

The CAS Registry Mumber 234766-45-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,3,4,7,6 and 6 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 234766-45:
(8*2)+(7*3)+(6*4)+(5*7)+(4*6)+(3*6)+(2*4)+(1*5)=151
151 % 10 = 1
So 234766-45-1 is a valid CAS Registry Number.

Control of copper(II) coordination geometry via supramolecular assembly of ligands in the solid state

White, David J.,Cronin, Leroy,Parsons, Simon,Robertson, Neil,Tasker, Peter A.,Bisson, Adrian P.

, p. 1107 - 1108 (1999)

The high density and strength of intermolecular hydrogen bonding between amine and sulfonamide units in the complex [Cu(Tstn)2] [TstnH = N-(3-aminopropyl)-4-methylbenzenesulfonamide] give rise to energetically unfavourable coordination geometries at the copper centres in the solid state, in a manner analogous to the entatic state forced on metal active sites in metalloenzymes through secondary and tertiary protein structures.
