Check Digit Verification of cas no

The CAS Registry Mumber 672907-39-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,2,9,0 and 7 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 672907-39:
(8*6)+(7*7)+(6*2)+(5*9)+(4*0)+(3*7)+(2*3)+(1*9)=190
190 % 10 = 0
So 672907-39-0 is a valid CAS Registry Number.

Synthesis of two linear PADRE conjugates bearing a deca- or pentadecasaccharide B epitope as potential synthetic vaccines against Shigella flexneri serotype 2a infection

Belot, Frederic,Guerreiro, Catherine,Baleux, Francoise,Mulard, Laurence A.

, p. 1625 - 1635 (2007/10/03)

The blockwise synthesis of the 2-aminoethyl glycosides of a deca- and a pentadecasaccharide made of two and three repeating units, respectively, of the Shigella flexneri serotype 2a specific polysaccharide is reported. The strategy relies on trifluoromethanesulfonic acid mediated glycosylation of a pentasaccharide building block acting as a glycosyl donor and a potential glycoside acceptor. Both targets were made available in amounts large enough for their subsequent conversion into glycoconjugates. Indeed, efficient elongation of the spacer through an acetylthioacetyl moiety and subsequent conjugation onto a Pan HLA DR-binding epitope (PADRE) T-cell-universal peptide resulted in two fully synthetic neoglycopeptides, which will be evaluated as potential vaccines against S. flexneri serotype 2a infections.

Blockwise Approach to Fragments of the O-Specific Polysaccharide of Shigella flexneri Serotype 2a: Convergent Synthesis of A Decasaccharide Representative of a Dimer of the Branched Repeating Unit

Belot, Frederic,Wright, Karen,Costachel, Corina,Phalipon, Armelle,Mulard, Laurence A.

, p. 1060 - 1074 (2007/10/03)

The D′A′B′(E′)C′DAB(E)C decasaccharide representative of a dimer of a frame-shifted pentasaccharide repeating unit of the O-specific polysaccharide of Shigella flexneri 2a was synthesized as its methyl glycoside by condensing a pentasaccharide donor (D′A′B′ (E′)C′) and a pentasaccharide acceptor (DAB(E)C-OMe). Several convergent routes to these two building blocks, involving either the AB linkage or the BC linkage as the disconnection site, were evaluated in comparison to the linear strategy. The latter was preferred. It is based on the use of the trichloroacetimidate chemistry. The target branched oligosaccharide was designed to probe the recognition at the molecular level of the natural polysaccharide by protective monoclonal antibodies.
