205927-03-3 Usage
Uses
Used in Chemical Catalysts Industry:
(S)-(-)-5,5',6,6'-TETRAMETHYL-3,3'-DI-TERT-BUTYL-1,1'-BIPHENYL-2,2'-DIOL is used as a chiral ligand for the preparation of monoand bidentate phosphites. These phosphites serve as catalysts in important chemical reactions, such as the hydroformylation of allyl cyanide, heterocyclic olefins, and asymmetric hydrogenation of dimethyl itaconate. The use of this ligand allows for the control of stereochemistry in these reactions, leading to the production of enantiomerically pure compounds, which are crucial in pharmaceuticals, agrochemicals, and other industries.
Reaction
The new Schrock-Hoveyda, chiral molybdenum catalyst can effect various modes of enantioselective olefin metathesis with excellent selectivity.
Check Digit Verification of cas no
The CAS Registry Mumber 205927-03-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,5,9,2 and 7 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 205927-03:
(8*2)+(7*0)+(6*5)+(5*9)+(4*2)+(3*7)+(2*0)+(1*3)=123
123 % 10 = 3
So 205927-03-3 is a valid CAS Registry Number.
