Check Digit Verification of cas no

The CAS Registry Mumber 117939-74-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,9,3 and 9 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 117939-74:
(8*1)+(7*1)+(6*7)+(5*9)+(4*3)+(3*9)+(2*7)+(1*4)=159
159 % 10 = 9
So 117939-74-9 is a valid CAS Registry Number.

Chiral sulfonated phosphines. Syntheses and use as ligands in asymmetric hydrogenation using an aqueous-organic two-phase solvent system

Amrani,Lecomte,Sinou,Bakos,Toth,Heil

, p. 542 - 547 (2008/10/08)

Sulfonation of chiral phosphines results in water-soluble ligands. The course of the reaction has been studied. Rhodium(I) catalysts formed with sulfonated diphosphines are efficient catalysts for the asymmetric hydrogenation of carbon-carbon, carbon-oxygen and carbon-nitrogen double bonds in aqueous-organic two-phase solvent systems. Sulfonated ligands afford a catalyst system, which can be reused without loss of enantioselectivity.
