It is a complex of titanium with two 4,5,6,7-tetrahydro-1-indenyl ligands and two methyl groups. (S,S)-ETHYLENEBIS-(4,5,6,7-TETRAHYDRO-1-INDENYL)-DIMETHYLTITANIUM(IV) is commonly used as a catalyst in stereoselective olefin polymerization reactions, specifically in the production of polyethylene and polypropylene. It is known for its ability to produce polymers with high stereoregularity, as well as for its high thermal stability and catalytic activity. Additionally, it has been studied for its potential applications in organic synthesis, pharmaceuticals, and other areas of materials science.
Check Digit Verification of cas no
The CAS Registry Mumber 115857-08-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,5,8,5 and 7 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 115857-08:
(8*1)+(7*1)+(6*5)+(5*8)+(4*5)+(3*7)+(2*0)+(1*8)=134
134 % 10 = 4
So 115857-08-4 is a valid CAS Registry Number.

An intramolecular titanium-catalyzed asymmetric Pauson - Khand type reaction
Hicks, Frederick A.,Buchwald, Stephen L.
, p. 7026 - 7033 (2007/10/03)
The development of the first catalytic asymmetric Pauson - Khand type cyclization of enynes is described. The active catalyst, (S,S)-(EBTHI)Ti(CO)2 (1), is generated in situ from (S,S)-(EBTHI)TiMe2 (2). A variety of 1,6-enynes can be
