113544-39-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 113544-39-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,5,4 and 4 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 113544-39:
(8*1)+(7*1)+(6*3)+(5*5)+(4*4)+(3*4)+(2*3)+(1*9)=101
101 % 10 = 1
So 113544-39-1 is a valid CAS Registry Number.

Suzuki-Miyaura coupling of aryl carbamates, carbonates, and sulfamates

Quasdorf, Kyle W.,Riener, Michelle,Petrova, Krastina V.,Garg, Neil K.

supporting information; experimental part, p. 17748 - 17749 (2010/04/01)

(Chemical Equation Presented) The first Suzuki-Miyaura cross-couplings of carbamates, carbonates, and sulfamates is described. The method provides a powerful means of using simple derivatives of phenol as precursors to polysubstituted aromatic compounds, as exemplified by a concise synthesis of the anti-inflammatory drug flurbiprofen.

ESTERS OF ARYLPROPIONIC ACIDS WITH 1,2:5,6-DI-O-ISOPROPYLIDENE- AND 1,2-O-ISOPROLYLIDENE-α-D-GLUCOFURANOSE

Svoboda, Jiri,Capek, Karel,Palecek, Jaroslav

, p. 766 - 774 (2007/10/02)

On fractional crystallization of 3-O-(2-(2-fluoro-4-biphenylyl)propionyl-, 3-O-(2-(4-isobutylphenyl)propionyl)- and 3-O-(2-(6-methoxy-2-naphthyl)propionyl)-1,2:5,6-di-O-isopropylidene-α-D-glucofuranoses V - VII optically pure R-diastereoisomers were isolated.The derivatives of 1,2-O-isopropylidene-α-D-glucofuranose obtained on partial deacetylation of esters V - VII were separated chromatographically to R and S-diastereoisomers.Their hydrolysis or transesterification afforded optically pure arylpropionic acids or their methyl esters, respectively.Kinetic resolutionof the acids gives rise to esters V - VII enriched in R-diastereoisomer.
