Check Digit Verification of cas no

The CAS Registry Mumber 59771-01-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,9,7,7 and 1 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 59771-01:
(7*5)+(6*9)+(5*7)+(4*7)+(3*1)+(2*0)+(1*1)=156
156 % 10 = 6
So 59771-01-6 is a valid CAS Registry Number.

Targeted fluorination with the fluoride ion by manganese-catalyzed decarboxylation

Huang, Xiongyi,Liu, Wei,Hooker, Jacob M.,Groves, John T.

, p. 5241 - 5245 (2015)

We describe the first catalytic decarboxylative fluorination reaction based on the nucleophilic fluoride ion. The reported method allows the facile replacement of various aliphatic carboxylic acid groups with fluorine. Moreover, the potential of this method for PET imaging has been demonstrated by the successful 18F labeling of a variety of carboxylic acids with radiochemical conversions up to 50-%, representing a targeted decarboxylative 18F labeling method with no-carrier-added [18F]fluoride. Mechanistic probes suggest that the reaction proceeds through the interaction of the manganese catalyst with iodine(III) carboxylates formed in situ from iodosylbenzene and the carboxylic acid substrates. Nucleophile first: An efficient manganese porphyrin catalyzed decarboxylative fluorination reaction based on a nucleophilic fluorine source is described. The potential of the described method for use in PET imaging has been demonstrated by the successful 18F labeling of various aliphatic carboxylic acids, representing the first decarboxylative 18F labeling method with no-carrier-added [18F]fluoride.

Process for the preparation of para-substituted derivatives of alpha-phenylpropionic acid

-

, (2008/06/13)

Pharmacologically useful alpha (para-alkylphenyl) propionic acids having anti-inflammatory, analgesic and antipyretic activity are prepared from the corresponding 1-haloethyl-para-alkylbenzene by converting same to a diethylacetal via a Grignard reaction, followed by the conversion of said acetal to the corresponding aldehyde by hydrolytic means, converting the said aldehyde to an oxime derivative and hydrolyzing the latter to the desired acid.
