28541-77-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 28541-77-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,5,4 and 1 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 28541-77:
(7*2)+(6*8)+(5*5)+(4*4)+(3*1)+(2*7)+(1*7)=127
127 % 10 = 7
So 28541-77-7 is a valid CAS Registry Number.

Preparation and characterization of glycopolymers with biphenyl spacers: Via Suzuki coupling reaction

Seto, Hirokazu,Tono, Takumi,Nagaoka, Akiko,Yamamoto, Mai,Hirohashi, Yumiko,Shinto, Hiroyuki

, p. 4474 - 4477 (2021/05/31)

Poly(vinylbiphenyl)s bearing glycoside ligands at the side chains were prepared using the Suzuku coupling reaction. Effects of glycoside reactant concentration, halide species, glycoside species, and catalyst species on the incorporation of glycoside ligand into the polymer were investigated. The obtained glycopolymers exhibited specific binding to proteins corresponding to the glycoside ligands. In addition, the biphenyl spacers formed by the Suzuki coupling reaction in the glycopolymer were fluorescent, whereas the polymer precursor was not.

Stereospecific α-D-mannosylation

Scott, Ian L.,Market, Robert V.,DeOrazio, Russell J.,Meckler, Harold,Kogan, Timothy P.

, p. 210 - 216 (2007/10/03)

The stereospecific formation of α-D-mannosyl glycosidic linkages has been achieved in high yield using tetra-O-pivaloyl-α-D-mannopyranosyl fluoride and boron trifluoride diethyl etherate in dichloromethane. Examples of the α-D-mannosylation of primary, secondary, benzylic and phenolic hydroxyl groups are described. Copyright (C) 1999 Elsevier Science Ltd.
