138688-77-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 138688-77-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,6,8 and 8 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 138688-77:
(8*1)+(7*3)+(6*8)+(5*6)+(4*8)+(3*8)+(2*7)+(1*7)=184
184 % 10 = 4
So 138688-77-4 is a valid CAS Registry Number.

One-Step TEMPO-Catalyzed and Water-Mediated Stereoselective Conversion of Glycals into 2-Azido-2-deoxysugars with a PIFA-Trimethylsilyl Azide Reagent System

Chennaiah, Ande,Vankar, Yashwant D.

supporting information, p. 2611 - 2614 (2018/05/17)

An unprecedented water-mediated and TEMPO-catalyzed, one-step, highly regiospecific and stereoselective functionalization of glycals to 2-azido-2-deoxysugars has been developed using a PIFA-Me3SiN3 reagent system in the presence of B

Synthesis of disaccharidic sub-units of a new series of heparin related oligosaccharides

La Ferla, Barbara,Lay, Luigi,Guerrini, Marco,Poletti, Laura,Panza, Luigi,Russo, Giovanni

, p. 9867 - 9880 (2007/10/03)

The chemical synthesis of disaccharides 1 and 2, useful building-blocks for the preparation of a new series of heparin related oligosaccharides containing the unusual sequence (GlcN-IdoA)(n), is described. In addition, the orthogonality of the protective groups would allow access to a wide array of differently sulfated oligosaccharides. As the simplest members of this new class of oligomer, the synthesis of sulfated disaccharides 3 and 4 fully deprotected is reported.

L-Iduronic acid derivatives as glycosyl donors

Tabeur, Christine,Machetto, Francoise,Mallet, Jean-Maurice,Duchaussoy, Philippe,Petitou, Maurice,Sinay, Pierre

, p. 253 - 276 (2007/10/03)

O-[Methyl (2-O-acetyl-3-O-benzyl-4-O-levulinyl-α, and β-L-idopyranosid)uronate]trichloroacetimidate and the corresponding n-pentenyl glycosides are efficient L-iduronic acid glycosyl donors. Both have been used for the high-yielding synthesis of basic disaccharide blocks which are useful for the subsequent synthesis of complex oligosaccharides related to heparin/heparan sulfate, and dermatan sulfate. In contrast, the corresponding thioethyl glycosides, thiophenyl glycosides, and fluoride, did not yield the expected disaccharides.
