247256-06-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 247256-06-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,7,2,5 and 6 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 247256-06:
(8*2)+(7*4)+(6*7)+(5*2)+(4*5)+(3*6)+(2*0)+(1*6)=140
140 % 10 = 0
So 247256-06-0 is a valid CAS Registry Number.

A new ligand containing a unique combination of backbone- and P-centered chirality: Synthesis, resolution and asymmetric catalysis using a chiral enantiopure 2,2'-biphospholene

Bienewald, Frank,Ricard, Louis,Mercier, Francois,Mathey, Francois

, p. 4701 - 4707 (1999)

Enantiopure 2,2'-bi(1-phenyl-3,4-dimethyl-2,5-dihydro-1H-phosphole) has been synthesized and tested in the rhodium-catalyzed asymmetric hydrogenation of α-acetamidocinnamic acid. Enantioselectivities up to 75% have been achieved. The absolute configuration of the biphospholene was determined by X-ray diffraction methods on a crystalline tungsten carbonyl derivative.
