109880-34-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 109880-34-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,8,8 and 0 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 109880-34:
(8*1)+(7*0)+(6*9)+(5*8)+(4*8)+(3*0)+(2*3)+(1*4)=144
144 % 10 = 4
So 109880-34-4 is a valid CAS Registry Number.

Palladium-catalyzed asymmetric addition of diarylphosphines to α,β-unsaturated sulfonic esters for the synthesis of chiral phosphine sulfonate compounds

Lu, Junzhu,Ye, Jinxing,Duan, Wei-Liang

, p. 5016 - 5019 (2013)

Highly stereoselective addition of diarylphosphines to α,β- unsaturated sulfonic esters catalyzed through a PCP pincer-Pd complex is developed to synthesize chiral phosphine sulfonic esters with excellent enantioselectivity (up to 99.5% ee). The transform
