439607-71-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 439607-71-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,9,6,0 and 7 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 439607-71:
(8*4)+(7*3)+(6*9)+(5*6)+(4*0)+(3*7)+(2*7)+(1*1)=173
173 % 10 = 3
So 439607-71-3 is a valid CAS Registry Number.

The formation and polymerization behavior of Ni(II) α-diimine complexes using various aluminum activators

Maldanis, Richard J,Wood, John S,Chandrasekaran,Rausch, Marvin D,Chien, James C.W

, p. 158 - 167 (2002)

Several Ni(II) α-diimine complexes have been synthesized and examined for ethylene and propylene polymerization in combination with different aluminum co-catalysts. The precatalysts used in the study were [ArN=C(Nap)-C(Nap)-C(Nap)=NAr]NiBr2 (Nap = 1,8-naphthdiyl) (1, Ar = 2,4,6-trimethylphenyl; 2, Ar = 2-tBu phenyl; 3, Ar = 2-iPr phenyl). These complexes were synthesized via a one-pot reaction where the ligand is formed via an acid catalyzed condensation followed by direct addition of nickel(II) bromide. The complexes were also prepared by a two-step procedure where the ligand was first formed by condensation between the appropriate aniline and acenapthoquinone, and the resulting ligand was then allowed to react with (1,2-dimethoxyethane) nickel(II) dibromide. X-ray structural studies of complexes 1 and 2 have been carried out. Diethylaluminum chloride (DEAC), and 1,3-dichloro-1,3-diisobutyldialuminoxane (DCDAO) show higher activities for ethylene and propylene polymerizations in combination with these Ni(II) α-diimine complexes than does polymethylaluminoxane (MAO). The molecular weight of the resulting polymers as well as their respective polydispersities and Tms are also presented. The polypropylenes obtained with 1/DEAC and 2/DEAC at 0 °C show similar rr triad percentage as previously reported for polypropylenes generated by MAO activated Ni(II) α-diimine complexes.
