Check Digit Verification of cas no
The CAS Registry Mumber 661-66-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,6 and 1 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 661-66:
(5*6)+(4*6)+(3*1)+(2*6)+(1*6)=75
75 % 10 = 5
So 661-66-5 is a valid CAS Registry Number.

Oligomers of vinyl phosphonic acid obtained by radical polymerization in the presence of halogenated chain transfer agent
Tayouo, Russell,David, Ghislain,Ameduri, Bruno,Boutevin, Bernard
experimental part, p. 545 - 548 (2010/09/04)
Two halogenated compounds, ICFCICF2Cl et BrCF 2CFCl-Br, were synthesized and characterized and were further used as chain transfer agents (CTAs) for the radical polymerization of vinyl phosphonic acid (VPA). Only BrCF2CFClBr was efficient CTA towards VPA as the chain transfer constant CT value of 1 was evaluated. This value clearly demonstrates that the chain-end of each VPA polymeric chain is BrCF 2CFCl group, which will allow to perform a dehalogenation from this group, leading to a new VPA macromonomer. Hence, VPA telomere were synthesized with Mn values ranging from 1800 to 6700 g/mol.
