Check Digit Verification of cas no

The CAS Registry Mumber 129867-63-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,8,6 and 7 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 129867-63:
(8*1)+(7*2)+(6*9)+(5*8)+(4*6)+(3*7)+(2*6)+(1*3)=176
176 % 10 = 6
So 129867-63-6 is a valid CAS Registry Number.

Synthesis of Chiral Atropoisomeric Square-planar Nickel(II) and Copper(II) Complexes formed by Macrocyclic Ligands containing Pendant Polyether Groups and a Quaternary Ammonium Group

Belokon, Yuri N.,Pritula, Ludmila K.,Tararov, Vitali I.,Bakhmutov, Vladimir I.,Struchkov, Yuri T.,et al.

, p. 1867 - 1872 (2007/10/02)

Novel copper(II) and nickel(II) complexes of macrocyclic Schiff bases formed from derivatives of N,N'-bis(2-benzoylphenyl)oxamide and 1,2-diaminoethane have been prepared.In one case, separation of atropoisomeric chiral complexes has been achieved by preparative chromatography on SiO2.Quaternization of some of the complexes with an excess of MeI affords chiral complexes possessing a positively charged quaternary ammonium group and polyether podands in addition to a weakly electrophilic metal site.
