5278-98-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5278-98-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,7 and 8 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 5278-98:
(6*5)+(5*2)+(4*7)+(3*8)+(2*9)+(1*8)=118
118 % 10 = 8
So 5278-98-8 is a valid CAS Registry Number.

Selective monoesterification of dicarboxylic acids catalysed by ion-exchange resins

Nishiguchi, Takeshi,Ishii, Yasuhiro,Fujisaki, Shizuo

, p. 3023 - 3027 (2007/10/03)

Symmetrical dicarboxylic acids with 4-14 carbon atoms gave selectively the corresponding monoesters in high yields in the transesterification catalysed by strongly acidic ion-exchange resins in ester-hydrocarbon mixtures. It was found that the rate of the esterification of the dicarboxylic acids is much higher than that of the monocarboxylic acids formed. This result can explain the high selectivity for the monoester formation and can also be explained by the existence of an aqueous layer on the surface of the resins. This method of selective esterification is quite simple and practical. The Royal Society of Chemistry 1999.

SELECTIVE MONOETHERIFICATION AND MONOESTERIFICATION OF DIOLS AND DIACIDS UNDER PHASE-TRANSFER CONDITIONS

Zerda, Jaime de la,Barak, Gabriela,Sasson, Yoel

, p. 1533 - 1536 (2007/10/02)

Research on the selectivity of etherification reactions of diols and esterification reactions of diacids by alkyl halides under phase-transfer catalysis has shown that under such conditions, selectivity of monoetherification increases in the order prim sec tert diols, though overall yield of monoether decreases from sec to tert diols.Monoesterification of diacids was accomplished with a high degree of selectivity.Optimal extraction of diols and diacids was found to correspond in general to chain lengths of around 5 carbons.This could mean that the complex formed between the catalyst and the anion to react is stabilized for certain carbon lengths by inner solvation in virtue of its spatial conformation.
