1291070-42-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1291070-42-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,1,0,7 and 0 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1291070-42:
(9*1)+(8*2)+(7*9)+(6*1)+(5*0)+(4*7)+(3*0)+(2*4)+(1*2)=132
132 % 10 = 2
So 1291070-42-2 is a valid CAS Registry Number.

SALALEN LIGANDS AND ORGANOMETALLIC COMPLEXES
-
, (2012/01/06)
Use of homogeneous catalytic systems which include as a pre-catalyst a complex of a Group IV metal and a salalen ligand in the polymerization of alpha-olefins, is disclosed. The alpha-olefin polymers obtained are characterized by controlled levels of tacticity. Also disclosed are novel salalen ligands and novel complexes thereof with Group IV metals.
