31506-18-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 31506-18-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,5,0 and 6 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 31506-18:
(7*3)+(6*1)+(5*5)+(4*0)+(3*6)+(2*1)+(1*8)=80
80 % 10 = 0
So 31506-18-0 is a valid CAS Registry Number.

Synthesis and Rearrangement Reactions of Ester-Linked Lignin-Carbohydrate Model Compounds

Li, Kaichang,Helm, Richard F.

, p. 2098 - 2103 (1995)

A series of ester-linked lignin-carbohydrate model compounds has been synthesized, which represent possible ester linkages of lignin to hemicellulose in wood through the carboxylic acid group of 4-O-methyl-α-D-glucopyranosiduronic acid moieties.The threo and erythro isomers of these compounds were prepared through an appropriate combination of protective and stereoselective transformations.Spectroscopic characterization of these esters revealed that the uronosyl group migrated between the primary (γ) and benzylic (α) positions of the lignin side chain in both acidic and neutral conditions.It has been determined that the migration equilibrium favors γ- over α-esters, with the reaction possibly proceeding through a six-membered ring intermediate.That uronosyl migrations occur favoring the γ-position suggests that the classical view of lignin-xylan ester linkages in wood needs to be reevaluated.Keywords: Acyl migration; lignin-carbohydrate complexes; NMR

SYNTHESIS OF METHYL ETHERS OF METHYL (METHYL α-D-GLUCOPYRANOSID) URONATE

Evtushenko, E. V.,Ovodov, Yu. S.

, p. 26 - 28 (2007/10/02)

Methyl (methyl α-D-glucopyranoisid)uronate (I) has been obtained by the catalytic oxidation of methyl α-D-glucopyranoside with oxygen in the presence of platinum on carbon with a yield of 31percent.The partial methylation of (I) followed by preparative liquid column chromatography on silica gel has provided a convenient method of obtaining all the methyl ethers of (I) in the individual state.
