Check Digit Verification of cas no

The CAS Registry Mumber 103878-42-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,8,7 and 8 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 103878-42:
(8*1)+(7*0)+(6*3)+(5*8)+(4*7)+(3*8)+(2*4)+(1*2)=128
128 % 10 = 8
So 103878-42-8 is a valid CAS Registry Number.

A convenient synthesis of nickel(II) and cobalt(II) complexes of unsymmetrical salen-type ligands and their application as catalysts for the oxidation of 2,6-dimethylphenol and 1,5-dihydroxynaphthalene by molecular oxygen

Adam, Waldemar,Saha-Moeller, Chantu R.,Ganeshpure, Pralhad A.

, p. 56 - 62 (2007/10/03)

Salen-type ligands 1-4 have been synthesized in high yields, from which the nickel(II) complexes 9-11 and the cobalt(II) complexes 12 and 13 have been prepared and characterized. The complexes have been assessed for their ability to activate molecular oxygen in the catalytic oxidation of phenols, namely, 2,6-dimethylphenol and 1,5-dihydroxynaphthalene. The nickel complexes 9-11 are inactive in the oxidation of the phenols but the cobalt complexes 12 and 13 show high catalytic activity.
