Check Digit Verification of cas no

The CAS Registry Mumber 170242-43-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,0,2,4 and 2 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 170242-43:
(8*1)+(7*7)+(6*0)+(5*2)+(4*4)+(3*2)+(2*4)+(1*3)=100
100 % 10 = 0
So 170242-43-0 is a valid CAS Registry Number.

Unbridged cyclopentadienyl-fluorenyl complexes of zirconium as catalysts for homogeneous olefin polymerization

Schmid, Michael A.,Alt, Helmut G.,Milius, Wolfgang

, p. 101 - 106 (1995)

The reaction of various lithium fluorenyl compounds, Li(C13H7R1R2) (R1R2=H, alkyl or aryl) (1a-1n), with C5H5ZrCl3 leads to unbridged fluorenyl complexes of the type (C5H5)C13H7R1R2)ZrCl2 (2a-2n) which can be converted to the corresponding metallocene dimethyl complexes (3a-3e).In combination with methylaluminoxane (MAO), 2a-2n show a higher catalytic activity as homogeneous eethylene polymerization catalysts than (C5H5)2ZrCl2.Compound 2d (R1=2-Me; R2=7-Me) was charcterized by an X-ray structure analysis.Keywords: Metallocene; Fluorenyl ligands; Olefin polymerization; Zirconium
