Check Digit Verification of cas no

The CAS Registry Mumber 138458-71-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,4,5 and 8 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 138458-71:
(8*1)+(7*3)+(6*8)+(5*4)+(4*5)+(3*8)+(2*7)+(1*1)=156
156 % 10 = 6
So 138458-71-6 is a valid CAS Registry Number.

Preparation of optically pure 1,2,5-triphenylphospholane. Use as ligand for enantioselective transition-metal catalysis

Fiaud,Legros

, p. 5089 - 5092 (1991)

Base-catalyzed isomerization of achiral (E,E)-1,2,5-triphenylphospholane oxide leads to the racemic (E,Z)-isomer. Resolution by Supercritical Fluid Chromatography (SFC) followed by reduction gives the two enantiomers. The activity of this new ligand is tested in palladium-catalyzed coupling of cyclohex-2-enyl acetate with nucleophiles.
