635683-83-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 635683-83-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,5,6,8 and 3 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 635683-83:
(8*6)+(7*3)+(6*5)+(5*6)+(4*8)+(3*3)+(2*8)+(1*3)=189
189 % 10 = 9
So 635683-83-9 is a valid CAS Registry Number.

A chromium catalyst for the polymerization of ethylene as a homogeneous model for the Phillips catalyst

MacAdams, Leonard A.,Buffone, Gerald P.,Incarvito, Christopher D.,Rheingold, Arnold L.,Theopold, Klaus H.

, p. 1082 - 1083 (2007/10/03)

A structurally characterized cationic chromium(III) alkyl featuring a bulky nacnac ligand catalyzes the polymerization of ethylene as well as the copolymerization of ethylene with α-olefins. This well-characterized homogeneous catalyst constitutes a structural as well as functional model of the widely used heterogeneous Phillips olefin polymerization catalyst. Copyright
