Check Digit Verification of cas no
The CAS Registry Mumber 894086-00-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,4,0,8 and 6 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 894086-00:
(8*8)+(7*9)+(6*4)+(5*0)+(4*8)+(3*6)+(2*0)+(1*0)=201
201 % 10 = 1
So 894086-00-1 is a valid CAS Registry Number.

Streamlined synthesis of the bippyphos family of ligands and cross-coupling applications

We describe the efficient preparation of Bippyphos, 1. The key precursor to Bippyphos, 5, was prepared via a one-pot bromination of diketone 2 followed by alkylation with pyrazole and condensation with phenylhydrazine. Lithiation of 5 and trapping with ditert-butylchlorophosphine afforded Bippyphos, 1. Using this approach we have prepared several derivatives of Bippyphos to probe the structure and activity relationships of this family of phosphine ligands. We also demonstrate the utility of these ligands in Pdcatalyzed amination reactions and other cross-coupling reactions.
