172275-99-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 172275-99-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,2,2,7 and 5 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 172275-99:
(8*1)+(7*7)+(6*2)+(5*2)+(4*7)+(3*5)+(2*9)+(1*9)=149
149 % 10 = 9
So 172275-99-9 is a valid CAS Registry Number.

A versatile approach to the synthesis of mannosamine glycosides

Alex, Catherine,Demchenko, Alexei V.,Visansirikul, Satsawat

, p. 6682 - 6695 (2020/10/02)

O-Picoloyl protecting groups at remote positions can affect the stereoselectivity of glycosylation by means of the H-bond-mediated aglycone delivery (HAD) pathway. A new practical method for the stereoselective synthesis of β-glycosides of mannosamine is reported. The presence of the O-picoloyl group at the C-3 position of a mannosamine donor can provide high or complete stereocontrol. The method was also utilized for the synthesis of a biologically relevant trisaccharide related to the capsular polysaccharide of Streptococcus pneumoniae serotype 4. Also reported herein is a method to achieve complete α-manno stereoselectivity with mannosamine donors equipped with 3-O-benzoyl group. This journal is

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
