Check Digit Verification of cas no

The CAS Registry Mumber 157103-03-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,1,0 and 3 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 157103-03:
(8*1)+(7*5)+(6*7)+(5*1)+(4*0)+(3*3)+(2*0)+(1*3)=102
102 % 10 = 2
So 157103-03-2 is a valid CAS Registry Number.

Synthesis of graft copolymers of polyethylene: grafting of fluorinated model compound oligomers

Boutevin, Bernard,Lusinchi, Jean-Marie,Pietrasanta, Yves,Robin, Jean-Jacques

, p. 205 - 210 (1994)

The condensation reaction of perfluorinated amines on to (succinic anhydride)-HDPE (high-density polyethylene) graft copolymer have been studied.Four different amine structures have been synthesized which have been analyzed by 1H NMR spectroscopy GC-MS methods.Model structures of succinimide and succinamic acid have been synthesized with each amine and analyzed by FT-IR spectroscopy in order to determine the structure of the compolymer obtained.A scale of reactivity has been deduced as a function of the amine structure.Grafting levels of copolymer have been determined by elemental analysis of fluorine.
