Check Digit Verification of cas no

The CAS Registry Mumber 131083-67-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,0,8 and 3 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 131083-67:
(8*1)+(7*3)+(6*1)+(5*0)+(4*8)+(3*3)+(2*6)+(1*7)=95
95 % 10 = 5
So 131083-67-5 is a valid CAS Registry Number.

Formation of disaccharides related to heparin and heparan sulfate by chemical modification of maltose

Glushka, John N.,Perlin, Arthur S.

, p. 305 - 321 (2007/10/02)

Maltose has been converted into 4-O-(2-amino-2-deoxy-α-D-glucopyranosyl)-L-idopyranuronic acid, 4-O-(2-amino-2-deoxy-α-D-glucopyranosyl)-D-glucopyranose, and 4-O-α-D-glucopyranosyl-L-idopyranose, the first two disaccharides being related structurally to biose sequences in heparin and heparan sulfate.Used as the starting material was a major product of the kinetic acetonation of maltose, namely, 2,3;5,6-di-O-isopropylidene-4-O-(4,6-O-isopropylidene-α-D-glucopyranosyl)-aldehydo-D-glucose dimethyl acetal.It was subjected to a sequence of transformations that included the introduction of a 2'-amino-2'-deoxy function into the glucosyl group, the inversion of C-5 in the glucose residue to give the L-ido configuration, oxidation at position 6, and cyclisation of the acyclic dimethyl acetal to give the desired pyranuronic acid.In the formation of the latter, the 5-O-levinoyl substituent was found to be less prone to acyl migration to O-6 than more conventional ester groups.The relative acid labilities of the O-isopropylidene and dimethyl acetal groups are compared, and conformations of the acyclic residues of some disaccharide derivatives are discussed.
