Check Digit Verification of cas no

The CAS Registry Mumber 174172-99-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,4,1,7 and 2 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 174172-99:
(8*1)+(7*7)+(6*4)+(5*1)+(4*7)+(3*2)+(2*9)+(1*9)=147
147 % 10 = 7
So 174172-99-7 is a valid CAS Registry Number.

Direct synthesis of diastereomerically pure glycosyl sulfonium salts

Mydock, Laurel K.,Kamat, Medha N.,Demchenko, Alexei V.

supporting information; scheme or table, p. 2928 - 2931 (2011/07/30)

It is reported that stable glycosyl sulfonium salts can be generated via direct anomeric S-methylation of ethylthioglycosides. Mechanistically, this pathway represents the first step in the activation of thioglycosides for glycosidation; however, it can f

PARTIAL SUBSTITUTION OF THIOGLYCOSIDES BY PHASE TRANSFER CATALYZED BENZOYLATION AND BENZYLATION

Garegg, Per J.,Kvarnstroem, Ingemar,Niklasson, Annika,Niklasson, Gunilla,Svensson, Stefan C. T.

, p. 933 - 954 (2007/10/02)

Partial substitution by phase transfer catalysis giving monobenzoylated and monobenzylated products from 2,3- and from 4,6-diols in ethyl 1-thio-D-hexopyranosides with the β-gluco, β-galacto- and α-manno-configurations are described.Two disaccharide thiog
