403657-31-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 403657-31-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,3,6,5 and 7 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 403657-31:
(8*4)+(7*0)+(6*3)+(5*6)+(4*5)+(3*7)+(2*3)+(1*1)=128
128 % 10 = 8
So 403657-31-8 is a valid CAS Registry Number.

New route to biaryl phosphanes with axial chirality as ligands for enantioselective hydrogenations

Driessen-Hoelscher, Birgit,Kralik, Joachim,Agel, Friederike,Steffens, Christian,Hu, Chunhua

, p. 979 - 982 (2007/10/03)

We have found a modular route for the synthesis of Cl-MeOBIPHEP ligands via the corresponding biphenol that allows us to introduce several substituents without the necessity to separate the enantiomers of each derivative. These new diphosphanes were used
