Check Digit Verification of cas no

The CAS Registry Mumber 124579-04-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,5,7 and 9 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 124579-04:
(8*1)+(7*2)+(6*4)+(5*5)+(4*7)+(3*9)+(2*0)+(1*4)=130
130 % 10 = 0
So 124579-04-0 is a valid CAS Registry Number.

Reactions of phenyl and ethyl 2-O-sulfonyl-1-thio-α-d-manno- and β-d-glucopyranosides with thionucleophiles

Liptak, Andras,Lazar, Laszlo,Borbas, Aniko,Antus, Sandor

experimental part, p. 2461 - 2467 (2010/03/03)

Persubstituted derivatives of phenyl and ethyl 2-O-sulfonyl-1-thio-α-d-manno- and β-d-glucopyranosides were synthesized and reacted either with PhSNa or with MeSNa. The phenyl-1-thio compounds afforded the dithio-1,2-cis-axial/equatorial-α-d-glucopyranosi

Synthesis of saponins with cholestanol, cholesterol, and friedelanol as aglycones

Schimmel, Joerg,Eleuterio, M. Ines Passos,Ritter, Gerd,Schmidt, Richard R.

, p. 1701 - 1721 (2007/10/03)

Procedures for the synthesis of branched Xylss(1→3)[Galss- (1→2)]-Glc and Xylss(1→3)[Galss(1→2)]-GlcUA trisaccharides ss-linked to the 3-O of cholesterol, cholestanol, and friedelanol, respectively, were developed. To this end, ss-selective glucosylation

Efficient methods for glycosidations with glycals - A key intermediate for the synthesis of mucin core 1-type O-glycan

Geiger, Jürgen,Barroca, Nadine,Schmidt

, p. 836 - 840 (2007/10/03)

The use of glycals as acceptors in glycosylation reactions is hampered by their sensitivity to acids. We report here on the successful use of mild Lewis acid [Sn(OTf)2] as catalyst for the glycosylation with O-glycosyl trichloroacetimidates and on the development of this method to construct a key intermediate for the synthesis of mucin type O-glycans. To this end, chemoselective nitration of O-glycosylated glycals, stereoselective threonine addition, and reduction of the nitro group to the amino group by an efficient procedure avoiding the use of an expensive catalyst was performed.

A NOVEL 1,3 O -> C SILYL REARRANGEMENT IN CARBOHYDRATE CHEMISTRY: SYNTHESIS OF α-D-GLYCOPYRANOSYLTRIMETHYLSILANES

Pedretti, Valerie,Veyrieres, Alain,Sinay, Pierre

, p. 77 - 88 (2007/10/02)

Reductive lithiation of 2-O-trimethylsilyl derivatives of phenyl thiogluco and -galactopyranosides gives rise to a 1,3 O -> C silyl migration leading to α-D-gluco and -galactopyranosyltrimethylsilanes in good yields.The expected β-elimination is observed

PREPARATION OF PYRANOID GLYCAL DERIVATIVES FROM PHENYL THIOGLYCOSIDES AND GLYCOSYL PHENYL SULPHONES

Fernandez-Mayoralas, Alfonso,Marra, Alberto,Trumtel, Michel,Veyrieres, Alain,Sinay, Pierre

, p. 81 - 96 (2007/10/02)

Phenyl thioglycopyranosides with various protecting groups (acetal, ether, ester) underwent reductive lithiation at C-1, followed by rapid elimination of the 2-substituent, when treated with lithium naphthalenide in tetrahydrofuran at low temperature.Thus

CONVENIENT SYNTHESES OF SUBSTITUTED PYRANOID GLYCALS FROM THIOPHENYL GLYCOSIDES AND GLYCOSYL PHENYLSULFONES

Fernandez-Mayoralas, Alfonso,Marra, Alberto,Trumtel, Michel,Veyrieres, Alain,Sinay, Pierre

, p. 2537 - 2540 (2007/10/02)

A series of substituted thiophenyl glycosides and glycosyl phenylsulfones were converted in high yield into glycals after reductive lithiation with lithium naphthalenide, followed by elimination of the substituent at C-2.
