155734-85-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 155734-85-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,7,3 and 4 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 155734-85:
(8*1)+(7*5)+(6*5)+(5*7)+(4*3)+(3*4)+(2*8)+(1*5)=153
153 % 10 = 3
So 155734-85-3 is a valid CAS Registry Number.

Enantioselective syntheses of 2-arylpropanoic acid non-steroidal antiinflammatory drugs and related compounds

Hamon, David P.G.,Massy-Westropp, Ralph A.,Newton, Josephine L.

, p. 12645 - 12660 (1995)

(S)-2-[4′-(2″-Methylpropyl)phenylpropanoic acid (ibuprofen) and (S)-2-(3′-benzoylphenyl)propanoic acid (ketoprofen) have been synthesised in high enantiomeric excess. Control of stereochemistry was achieved by a combination of Sharpless epoxidalion followed by catalytic hydrogenolysis of the introduced benzylic epoxide oxygen bond. Also, the coupling of organic compounds in the presence of palladium with enantiopure 2-(3-iodophenyl)propanoic and 2-(4-iodophenyl)propanoic acids, prepared by the methodology above, is a general method for the synthesis of optically active arylpropanoic acids.
