139446-54-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 139446-54-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,4,4 and 6 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 139446-54:
(8*1)+(7*3)+(6*9)+(5*4)+(4*4)+(3*6)+(2*5)+(1*4)=151
151 % 10 = 1
So 139446-54-1 is a valid CAS Registry Number.

Rh-catalyzed highly enantioselective synthesis of 3-arylbutanoic acids

Sun, Xianfeng,Zhou, Le,Wang, Chun-Jiang,Zhang, Xumu

, p. 2623 - 2626 (2008/02/13)

(Chemical Equation Presented) It's in the mix: The reaction conditions - catalyst, additive, and solvent - have been optimized for the asymmetric hydrogenation of 3-aryl-3-butenoic acids. The rigid, chiral bisphospholane ligand (SP,RC)-DuanPhos is crucial to achieving high enantioselectivity.

3-Aryl-3-butenoic Acids and Their Esters: Practical Synthesis from Diketene by the Palladium-Catalyzed Grignard Coupling Reaction and Application as Monomers for the Radical Copolymerization with Styrene

Itoh, Kenji,Harada, Tatsumi,Nagashima, Hideo

, p. 3746 - 3748 (2007/10/02)

Treatment of arylmagnesium bromide with an equimolar amount of zinc chloride followed by the reaction with diketene in the presence of a catalytic amount of PdCl2(PPh3)2 provided an improved synthetic method for 3-aryl-3-butenoic acid in a large scale.App
