Check Digit Verification of cas no

The CAS Registry Mumber 357604-80-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,5,7,6,0 and 4 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 357604-80:
(8*3)+(7*5)+(6*7)+(5*6)+(4*0)+(3*4)+(2*8)+(1*0)=159
159 % 10 = 9
So 357604-80-9 is a valid CAS Registry Number.

Amido functionalized ansa half-sandwich dichloride complexes of titanium, zirconium and hafnium with alkyl and ω-alkenyl substituents as homogeneous and self-immobilizing catalyst precursors for ethylene polymerization

Alt, Helmut G.,Reb, Alexander,Milius, Wolfgang,Weis, Annette

, p. 169 - 182 (2001)

A total of 24 amido functionalized ansa half-sandwich dichloride complexes of titanium, zirconium and hafnium with cyclopentadienyl or indenyl ligands have been prepared, characterized and used for catalytic ethylene polymerization. Alkyl and ω-alkenyl substituents on the aromatic system influence the polymerization activity of the catalysts and the properties of the produced polyethylene. After activation with methylalumoxane the ω-alkenyl substituted catalysts show self-immobilization in ethylene polymerization.
