205927-03-3 Usage

Reaction

The new Schrock-Hoveyda, chiral molybdenum catalyst can effect various modes of enantioselective olefin metathesis with excellent selectivity.

General Description

(S)-5,5′,6,6′-Tetramethyl-3,3′-di-tert-butyl-1,1′-biphenyl-2,2′-diol, a biphenyl chiral ligand is used to prepare mono- and bidentate phosphites applicable as catalysts in the hydroformylation of allyl cyanide, heterocyclic olefins, and asymmetric hydrogenation of dimethyl itaconate.

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.
