69573-11-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 69573-11-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,5,7 and 3 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 69573-11:
(7*6)+(6*9)+(5*5)+(4*7)+(3*3)+(2*1)+(1*1)=161
161 % 10 = 1
So 69573-11-1 is a valid CAS Registry Number.

Method for enantioselective synthesis of phosphorus-stereogenic phosphines

-

Page/Page column 30, (2012/06/16)

The present invention relates to a process for preparing an enantioenriched phosphorus-stereogenic, tertiary phosphine. Secondary phosphines are contacted with an alkyl halide and base in the presence of a chiral metal catalyst thereby producing the enantioenriched phosphorus-stereogenic, tertiary phosphine for subsequent use in homogeneous catalysis reactions.
