1220958-47-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1220958-47-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,0,9,5 and 8 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1220958-47:
(9*1)+(8*2)+(7*2)+(6*0)+(5*9)+(4*5)+(3*8)+(2*4)+(1*7)=143
143 % 10 = 3
So 1220958-47-3 is a valid CAS Registry Number.

Silicon-bridged tetramethylcyclopentadienyl-phenoxy complexes of tantalum: Preparation and alkylation of Et2Si(η5-C 5Me4)(3-tBu-5-Me-2-C6H 2O)TaCl3 and generation of its cationic Complex

, p. 2080 - 2084 (2010)

A tantalum complex of a silicon-bridged tetramethylcyclopentadienyl-phenoxy ligand, Et2Si(η5-C5Me4)(3- tBu-5-Me-2-C6H2O)TaCl3 (2), was prepared by treating TaCl5 with the dilithium salt generated by reaction of the corresponding ligand 1 with nBuLi in the presence of Et3N in heptane. The molecular structure of 2, as confirmed by X-ray analysis, showed a four-legged piano-stool geometry around the tantalum atom and slightly twisted ligand architecture with a bridging diethylsilylene unit. The tantalum complex 2 exhibited moderate catalytic activities for copolymerization of ethylene and 1-hexene in the presence of iBu3Al/Ph 3C[B(C6F5)4]. The methylation reaction of the trichlorotantalum complex 2 afforded the corresponding trimethyltantalum complex 4. Cationic dimethyltantalum species were generated by treating 4 with an equimolar amount of Ph3C[B(C6F 5)4] or B(C6F5)3 and found to be thermally stable in o-dichlorobenzene-d4, even at elevated temperature.
