146814-57-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 146814-57-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,6,8,1 and 4 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 146814-57:
(8*1)+(7*4)+(6*6)+(5*8)+(4*1)+(3*4)+(2*5)+(1*7)=145
145 % 10 = 5
So 146814-57-5 is a valid CAS Registry Number.

meso-Me2Si(1-indenyl)2ZrCl2/ methylalumoxane catalyzed polymerization of the ethylene to ethyl-branched polyethylene

Melillo, Gianluca,Izzo, Lorella,Centore, Roberto,Tuzi, Angela,Voskoboynikov, Alexander Z.,Oliva, Leone

, p. 29 - 33 (2008/10/09)

The meso ansa zirconocene with dimethylsilyl bridge, activated by methylalumoxane, catalyses the ethylene polymerization, producing ethyl-branched polyethylene. With respect to the polymers obtained with the previously investigated meso zirconocenes, we have found higher branching amount and lower molecular weight. The rapid β-H transfer from the growing chain to the coordinated monomer could account for both these features of the polymer. The investigation on the structural parameters of the complex, through X-ray diffraction analysis, and on the electrophilicity of the cationic center, through NMR experiments, suggests, as a possible rationalization of this behavior, the obstruction in the inward site.
