Check Digit Verification of cas no
The CAS Registry Mumber 161790-50-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,7,9 and 0 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 161790-50:
(8*1)+(7*6)+(6*1)+(5*7)+(4*9)+(3*0)+(2*5)+(1*0)=137
137 % 10 = 7
So 161790-50-7 is a valid CAS Registry Number.

Asymmetric hydrogenation of α,β-unsaturated carboxylic acids catalyzed by ruthenium(II) complexes of spirobifluorene diphosphine (SFDP) ligands

The ruthenium diacetate complexes ligated by chiral spirobifluorene diphosphines (SFDP) were very effective catalysts for the asymmetric hydrogenation of tiglic acid derivatives and α-methylcinnamic acid derivatives with high activities and excellent enantioselectivities (up to 98% ee). The α-aryloxybutenoic acids can also be hydrogenated by these catalysts to provide the corresponding saturated α-aryloxybutanoic acids in high yields (89-93%) and enantioselectivities (up to 95% ee). In this reaction, the SFDP ligand with para-methyl groups on the P-phenyl rings gave the best results.
