23346-82-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 23346-82-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,3,4 and 6 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 23346-82:
(7*2)+(6*3)+(5*3)+(4*4)+(3*6)+(2*8)+(1*2)=99
99 % 10 = 9
So 23346-82-9 is a valid CAS Registry Number.

N-bromosuccinimide/dibromodimethylhydantoin in aqueous base: A practical method for the bromination of activated benzoic acids

Auerbach, Joseph,Weissman, Steven A.,Blacklock, Thomas J.,Angeles, Marshall R.,Hoogsteen, Karst

, p. 931 - 934 (1993)

A new bromination method employing NBS or dibromodimethylhydantoin in aqueous base is described for the synthesis of 3-bromo-2,6-dimethoxybenzoic acid (1) and other monobrominated alkoxybenzoic acids.

Access to Atropisomerically En-riched Biaryls by the Coupling of Aryllithiums with Arynes under Control by Homochiral Oxazolines

Yalcouye, Boubacar,Berthelot-Bréhier, Ana?s,Augros, David,Panossian, Armen,Choppin, Sabine,Chessé, Matthieu,Colobert, Fran?oise,Leroux, Frédéric R.

supporting information, p. 725 - 732 (2017/01/18)

We report the preparation of axially stereoenriched biphenyls by the coupling of in situ generated aryllithiums and arynes using chiral oxazoline auxiliaries. The design of the aryne precursors, the choice of oxazoline and the reaction conditions were key to accessing the desired, highly substituted, atropisomerically enriched biarylic products. In one case, the two atropo-diastereomers could be obtained in isomerically pure form by column chromatographic separation and their absolute configurations established by X-ray crystallography. The stereoselectivity of the reaction seems to be governed by subtle parameters.
