18423-66-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 18423-66-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,4,2 and 3 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 18423-66:
(7*1)+(6*8)+(5*4)+(4*2)+(3*3)+(2*6)+(1*6)=110
110 % 10 = 0
So 18423-66-0 is a valid CAS Registry Number.

A new efficient access to glycono-1,4-lactones by oxidation of unprotected itols by catalytic hydrogen transfer with RhH(PPh3)4-benzalacetone system

Isaac,Aizel,Stasik,Wadouachi,Beaupère

, p. 475 - 476 (2007/10/03)

Treatment of unprotected pentitols and hexitols with RhH(PPh3)4-benzalacetone system leads exclusively to glycono-1,4-lactones in 60-96% yield.

Stereocontrol in organic synthesis using silicon-containing compounds. Syntheses of (±)-2-deoxyribonolactone and (±)-arabonolactone

Fleming, Ian,Ghosh, Sunil K.

, p. 2711 - 2720 (2007/10/03)

Samarium iodide reacts with methyl (Z)-3-dimethyl(4-methylphenyl)silylprop-2-enoate 5b to give dimethyl (3RS,4SR)-3,4-bis[dimethyl(4-methylphenyl)silyl]hexane-1,6-dioate 8b with high stereoselectivity. This meso diester can be converted into (3RS,4SR)-3,4-bis[dimethyl(4-methylphenyl)silyl]pentan-5-olide 16 by Dieckmann cyclisation, demethoxycarbonylation and Baeyer-Villiger reaction. Silyl-to-hydroxy conversion and relactonisation gave (±)-deoxyribonolactone, and anti-selective enolate hydroxylation followed by silyl-to-hydroxy conversion gave (±)-arabonolactone. An attempt to synthesise sugars with the relative configuration (3RS,4RS) was thwarted by an unprecedented retention of configuration at the migration origin in the cationic rearrangement of (3RS,4SR)-3,4-bis[dimethyl(4-methylphenyl)silyl]-5-hydroxypentanoic acid 28 to (3RS,4SR)-3,5-bis[dimethyl(4-methylphenyl)silyl]pentan-1,4-olide 30.

Stereoselective Samarium(II)-induced Coupling of β-Silylacrylic Esters: a Synthesis of (+/-)-2-Deoxyribonolactone

Fleming, Ian,Ghosh, Sunil K.

, p. 1775 - 1777 (2007/10/02)

Samarium iodide converts the β-silylacrylate 1c with high stereoselectivity into the racemic diester 2c, from which (+/-)deoxyribonolactone 11 can be prepared.

Synthesis of D-erythroascorbic acid from D-glucose

Gan, Li-Xian,Seib, Paul A.

, p. 117 - 126 (2007/10/02)

Reaction of a 4:1 mixture of D-ribono- and D-arabinono-1,4-lactones with benzaldehyde and hydrochloric acid gave 59percent crystalline 3,4-O-benzylidene-D-ribono-1,5-lactone.This acetal was oxidized with manganese dioxide in acetone to its 2-keto-derivative (6) in 76percent yield.Acid-catalyzed methanolysis of 6 gave a syrupy mixture of products, which upon tautomerization in hot methanolic sodium acetate followed by removal of sodium ions gave 78percent D-erythroascorbic acid (7).The overall yield of 7 starting from D-glucose was 20percent.
