Check Digit Verification of cas no

The CAS Registry Mumber 1448540-27-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,8,5,4 and 0 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1448540-27:
(9*1)+(8*4)+(7*4)+(6*8)+(5*5)+(4*4)+(3*0)+(2*2)+(1*7)=169
169 % 10 = 9
So 1448540-27-9 is a valid CAS Registry Number.

Synthesis and immunological characterization of modified hyaluronic acid hexasaccharide conjugates

Gu, Guofeng,Adabala, Pal John Pal,Szczepina, Monica G.,Borrelli, Silvia,Pinto, B. Mario

, p. 8004 - 8019 (2013)

The synthesis of a tetanus toxoid (TT)-conjugate of a hyaluronic acid (HA) hexasaccharide is described. The compound was intended for use in monitoring HA levels as a disease marker and as a potential vaccine against Group A Streptococcus (GAS) infections. We also report the synthesis of a chemically modified HA-hexasaccharide-TT conjugate in which the N-acetyl moiety of the N-acetyl-d-glucosamine residue is replaced with an N-propionyl unit in order to enhance immunogenicity. The oligosaccharides are synthesized in a convergent manner. The TT-conjugate syntheses rely on the reaction of the amines on the 6-aminohexyl aglycon of the hexasaccharides with diethyl squarate to give the monoethyl squarate adducts. Subsequent reactions with lysine ε-amino groups on TT then give the glycoconjugates containing an average of 8 hexasaccharide haptens per TT molecule. Immunological studies in mice show very similar antibody responses with both conjugates, suggesting that the N-acetyl groups of the glucosaminyl residues of the HA-hexasaccharide are not a critical part of the epitope recognized by the anti-HA polyclonal immune response. Furthermore, it would appear that the N-acyl moieties are not in close contact with the amino acid residues of the antibody combining sites.
