Check Digit Verification of cas no

The CAS Registry Mumber 183613-29-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,3,6,1 and 3 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 183613-29:
(8*1)+(7*8)+(6*3)+(5*6)+(4*1)+(3*3)+(2*2)+(1*9)=138
138 % 10 = 8
So 183613-29-8 is a valid CAS Registry Number.

Synthesis of a hexasaccharide fragment of group E streptococci polysaccharide and the tetrasaccharide repeating unit of E. coli O7:K98:H6

Zeng, Youlin,Kong, Fanzuo

, p. 1503 - 1510 (2007/10/03)

Syntheses of a hexasaccharide, the dimer of the repeating unit of the group E streptococci polysaccharide, and a tetrasaccharide, the repeating unit of the E. coli O7:K98:H6, were achieved by constructing alternate α-L-(1→2) - and α-L-(1→3)-linked L-rhamnopyranose backbones and substituting with β-linked D-glucopyranose side chains for the former, and a D-glucopyranosyluronate branch for the latter, respectively, at O-2 of the L-rhamnose ring.
