Check Digit Verification of cas no

The CAS Registry Mumber 204918-63-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,4,9,1 and 8 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 204918-63:
(8*2)+(7*0)+(6*4)+(5*9)+(4*1)+(3*8)+(2*6)+(1*3)=128
128 % 10 = 8
So 204918-63-8 is a valid CAS Registry Number.

Regioselective glycosylation method using partially protected arabino- and galactofuranosyl thioglycosides as key glycosylating substrates and its application to one-pot synthesis of oligofuranoses

Deng, Li-Min,Liu, Xia,Liang, Xing-Yong,Yang, Jin-Song

experimental part, p. 3025 - 3037 (2012/06/18)

We describe in this paper the development of a novel regioselective furanosylation methodology using partially protected furanosyl thioglycosides as central glycosylating building blocks and its application in the efficient one-pot synthesis of a series of linear and branched-type arabino- and galactofuranoside fragments structurally related to the cell wall polysaccharides of Mycobacterium tuberculosis, Streptococcus pneumoniae serostype 35A, and sugar beet.

Arabinofuranosyl oligosaccharides from mycobacteria: Synthesis and effect of glycosylation on ring conformation and hydroxymethyl group rotamer populations

D'Souza, Francis W.,Ayers, Joseph D.,McCarren, Patrick R.,Lowary, Todd L.

, p. 1251 - 1260 (2007/10/03)

A series of αD-arabinofuranosyl oligosaccharides (2-8) that are fragments of the arabinan portions of two polysaccharides present in the cell wall of Mycobacterium tuberculosis have been synthesized. Preparation of the oligosaccharides involved the sequen
