Check Digit Verification of cas no
The CAS Registry Mumber 656800-67-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,5,6,8,0 and 0 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 656800-67:
(8*6)+(7*5)+(6*6)+(5*8)+(4*0)+(3*0)+(2*6)+(1*7)=178
178 % 10 = 8
So 656800-67-8 is a valid CAS Registry Number.

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.
