Check Digit Verification of cas no

The CAS Registry Mumber 405521-16-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,5,5,2 and 1 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 405521-16:
(8*4)+(7*0)+(6*5)+(5*5)+(4*2)+(3*1)+(2*1)+(1*6)=106
106 % 10 = 6
So 405521-16-6 is a valid CAS Registry Number.

Synthesis and polymerization in unsaturated Co β-diketonates

Zub,Berezhnitskaya,Savchenko,Voloshanovskii,Gudich,Mazurenko,Shevchenko

, p. 709 - 712 (2004)

Polymerization of some unsaturated β-diketonates of cobalt containing double bonds both unconjugated and conjugated with a metal cycle. Unlike monomeric complexes, cobalt in metal-containing polymers was shown to have tetrahedral structure of the coordination polyhedron. The kinetic parameters of polymerization depend on electronic and steric properties of β-diketonates.
