Check Digit Verification of cas no

The CAS Registry Mumber 864715-99-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,4,7,1 and 5 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 864715-99:
(8*8)+(7*6)+(6*4)+(5*7)+(4*1)+(3*5)+(2*9)+(1*9)=211
211 % 10 = 1
So 864715-99-1 is a valid CAS Registry Number.

A novel semi-fluorinated graft copolymer containing perfluorocyclobutyl aryl ether-based backbone

Zhang, Sen,Liu, Hao,Deng, Yan,Huang, Xiaoyu

, p. 184 - 189 (2012/02/05)

The synthesis of a series of novel semi-fluorinated graft copolymers bearing perfluorocyclobutyl (PFCB) aryl ether-based backbone and polystyrene side chains is described. This work initially focused on the synthesis of a trifluorovinyl ether (TFVE) monomer containing a bromine atom, which could be employed as an initiating site for atom transfer radical polymerization (ATRP). Thermal cyclopolymerization of this TFVE monomer provided a macromolecular initiator followed by subsequent initiating ATRP of styrene to afford the desired PFCB aryl ether-based graft copolymers.
