176690-90-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 176690-90-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,6,6,9 and 0 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 176690-90:
(8*1)+(7*7)+(6*6)+(5*6)+(4*9)+(3*0)+(2*9)+(1*0)=177
177 % 10 = 7
So 176690-90-7 is a valid CAS Registry Number.

3- and 4-uloses derived from N-acetyl- D -glucosamine: A unique pair of complementary organocatalysts for asymmetric epoxidation of alkenes

Schoeberl, Christof,Jaeger, Volker

supporting information; experimental part, p. 790 - 796 (2012/05/04)

The 4-ulose and the 3-ulose, both derived in two steps from the α-methyl glycoside of N-acetyl-D-glucosamine (GlcNAc), act as organocatalysts in the asymmetric epoxidation of alkenes, with unprecedented complementary enantioselectivity. The best results are found with α,β-unsaturated esters as substrates, with enantiomeric ratios up to 90:10 and 11:89, respectively. Copyright

Synthesis and conformational analysis of glycomimetic analogs of thiochitobiose

Fettke, Anja,Peikow, Dirk,Peter, Martin G.,Kleinpeter, Erich

supporting information; experimental part, p. 4356 - 4366 (2009/10/09)

The synthesis of six analogs of N,N′-diacetylchitobiose is reported, including a novel transglycosylation reaction for the preparation of S-aryl thioglycosides. The conformations of the compounds were studied by a combination of NMR spectroscopy and molec

Synthesis of 4-deoxy-4-fluoro analogues of 2-acetamido-2-deoxy-D-glucose and 2-acetamido-2-deoxy-D-galactose and their effects on cellular glycosaminoglycan biosynthesis

Berkin, Ali,Szarek, Walter A.,Kisilevsky, Robert

, p. 250 - 263 (2007/10/03)

4-Deoxy-4-fluoro analogues of 2-acetamido-2-deoxy-D-glucose and 2-acetamido-2-deoxy-D-galactose were synthesized and evaluated as inhibitors of hepatic glycosaminoglycan biosynthesis. 2-Acetamido-1,3,6-tri-O-acetyl-2,4-dideoxy-4-fluoro-D-glucopyranose (16) exhibited a reduction of [3H]GlcN and [35S]SO4 incorporation into hepatocyte cellular glycosaminoglycans to 12 and 18%, respectively, of the control cells, at 1.0 mM. Similarly, 2-acetamido-1,3,6-tri-O-acetyl-2,4-dideoxy-4-fluoro-D-galactopyranose (31) exhibited a reduction of [3H]GlcN and [35S]SO4 incorporation to 1 and 9%, respectively, of the control cells, at 1.0 mM. Unlike 16, 31 exhibited a reduction of [14C]Leu incorporation into cellular protein to 57% of control cells, at 1.0 mM. Copyright (C) 2000 Elsevier Science Ltd.
