289670-84-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 289670-84-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,9,6,7 and 0 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 289670-84:
(8*2)+(7*8)+(6*9)+(5*6)+(4*7)+(3*0)+(2*8)+(1*4)=204
204 % 10 = 4
So 289670-84-4 is a valid CAS Registry Number.

Asymmetric hydrogenation of ketones using a ruthenium(II) catalyst containing BINOL-derived monodonor phosphorus-donor ligands

Xu, Yingjian,Alcock, Nat W.,Clarkson, Guy J.,Docherty, Gordon,Woodward, Gary,Wills, Martin

, p. 4105 - 4107 (2004)

(Chemical Equation Presented) A series of ruthenium(II) complexes containing BINOL-based monodonor phosphorus ligands have been prepared and applied to the asymmetric catalysis of the hydrogenation of aryl/alkyl ketones. The best ligands for this application are those which contain an aromatic groups with either a methoxide or bromide on the ortho position. Using these ligands, alcohols with ee's of up to 99% are formed.

Highly efficient phosphapalladacyclic catalysts for the hydroarylation of norbornene

Brunel, Jean Michel,Heumann, Andreas,Buono, Gerard

, p. 1946 - 1949 (2007/10/03)

Exceptionally high turnover numbers of up to 196 x 106 moles of product per mole of catalyst, turnover frequencies of up to 12 x 106 moles of product per mole of catalyst per hour, and yields of 98% were achieved in the hydroarylatio
