Check Digit Verification of cas no

The CAS Registry Mumber 18118-75-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,1,1 and 8 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 18118-75:
(7*1)+(6*8)+(5*1)+(4*1)+(3*8)+(2*7)+(1*5)=107
107 % 10 = 7
So 18118-75-7 is a valid CAS Registry Number.

Heterogeneous structure of O-antigenic part of lipopolysaccharide of Salmonella telaviv (Serogroup O:28) containing 3-acetamido-3,6-dideoxy-D- glucopyranose

Kumirska,Dziadziuszko,Czerwicka,Lubecka,Kunikowska,Siedlecka,Stepnowski

experimental part, p. 780 - 790 (2012/01/19)

The O-polysaccharide of Salmonella Telaviv was obtained by mild acid degradation of the lipopolysaccharide and studied by chemical methods (sugar and methylation analyses, Smith degradation, de-O-acetylation) and NMR spectroscopy. The structure of the O-polysaccharide was established. The repeating units that are proximal to the lipopolysaccharide core region mostly have a digalactose side chain and lack glucose, whereas those at the other end of the chain mostly do bear glucose but are devoid of the disaccharide side chain. This is the first structure established for the O-polysaccharide of a Salmonella serogroup O:28 (formerly M) strain characterized by subfactors O281 and O282. Knowledge of this structure and the structure of the O-polysaccharide of Salmonella Dakar (O281, O28 3) established earlier is crucial for determination of the exact structures associated with subfactors O281, O282, and O283 and elucidation of the genetic basis of the close relationship between Escherichia coli O71 and S. enterica O:28 O-antigens.
