Check Digit Verification of cas no

The CAS Registry Mumber 138948-58-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,9,4 and 8 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 138948-58:
(8*1)+(7*3)+(6*8)+(5*9)+(4*4)+(3*8)+(2*5)+(1*8)=180
180 % 10 = 0
So 138948-58-0 is a valid CAS Registry Number.

Decarboxylative Acetoxylation of Aliphatic Carboxylic Acids

Senaweera, Sameera,Cartwright, Kaitie C.,Tunge, Jon A.

, p. 12553 - 12561 (2019/10/14)

Organic molecules bearing acetoxy moieties are important functionalities in natural products, drugs, and agricultural chemicals. Synthesis of such molecules via transition metal-catalyzed C-O bond formation can be achieved in the presence of a carefully chosen directing group to alleviate the challenges associated with regioselectivity. An alternative approach is to use ubiquitous carboxylic acids as starting materials and perform a decarboxylative coupling. Herein, we report conditions for a photocatalytic decarboxylative C-O bond formation reaction that provides rapid and facile access to the corresponding acetoxylated products. Mechanistic investigations suggest that the reaction operates via oxidation of the carboxylate followed by rapid decarboxylation and oxidation by Cu(OAc)2

Highly enantioselective aminoacylase-catalyzed transesterification of secondary alcohols

Bakker,Spruijt,Van Rantwijk,Sheldon

, p. 1801 - 1808 (2007/10/03)

The aminoacylase (N-acyl-L-amino acid amidohydrolase; E.C. 3.5.1.14) from Aspergillus melleus, a readily available inexpensive enzyme, catalyzes the transesterification of a wide range of chiral secondary arylalkanols with essentially absolute stereoselectivity (E> 500). Moreover, the productivities obtained with 1-phenylethanol, 1-phenylpropanol, 1-(1-naphthyl)ethanol and 1- (2-naphthyl)ethanol were substantially higher than those in the corresponding lipase-catalyzed transesterifications.

LIPASE-CATALYZED IRREVERSIBLE TRANSESTERIFICATION USING ENOL ESTERS: XAD-8 IMMOBILIZED LIPOPROTEIN LIPASE-CATALYZED RESOLUTION OF SECONDARY ALCOHOLS

Hsu, Shu-Hui,Wu, Shihn-Sheng,Wang, Yi-Fong,Wong, Chi-Huey

, p. 6403 - 6406 (2007/10/02)

Procedures for preparation of XAD-8 immobilized lipoprotein lipase and the resolution of secondary alcohols of synthetic value in organic solvents using this immobilized enzyme have been developed.
