Check Digit Verification of cas no

The CAS Registry Mumber 1045-11-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,4 and 5 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1045-11:
(6*1)+(5*0)+(4*4)+(3*5)+(2*1)+(1*1)=40
40 % 10 = 0
So 1045-11-0 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 (2007/10/02)

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.
