856413-61-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 856413-61-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,6,4,1 and 3 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 856413-61:
(8*8)+(7*5)+(6*6)+(5*4)+(4*1)+(3*3)+(2*6)+(1*1)=181
181 % 10 = 1
So 856413-61-1 is a valid CAS Registry Number.

Asymmetric ansa-zirconocenes containing a 2-methyl-4-aryltetrahydroindacene fragment: Synthesis, structure, and catalytic activity in propylene polymerization and copolymerization

Nifant'ev, Ilya E.,Ivchenko, Pavel V.,Bagrov, Vladimir V.,Okumura, Yoshikuni,Elder, Michael,Churakov, Andrei V.

, p. 5744 - 5752 (2012/01/14)

A set of asymmetric bis-indenyl zirconium SiMe2-bridged ansa-complexes, containing 2-isopropyl-4-arylindenyl and 2-methyl-4- aryltetrahydroindacenyl fragments, have been synthesized. These complexes demonstrate better catalytic activity, stereoselectivty, and polymer molecular weight capability in propylene homo-and copolymerization in comparison to analogues without a tetrahydroindacenyl fragment.
