172847-90-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 172847-90-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,2,8,4 and 7 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 172847-90:
(8*1)+(7*7)+(6*2)+(5*8)+(4*4)+(3*7)+(2*9)+(1*0)=164
164 % 10 = 4
So 172847-90-4 is a valid CAS Registry Number.

METHOD FOR PRODUCING SUGAR HAVING SULFATE GROUP AND/OR PHOSPHATE GROUP

-

Page/Page column 0211; 0212, (2020/03/09)

An object of the invention is to provide a method of uniformly and efficiently producing a saccharide having a sulfate group and/or a phosphate group in the molecule, or a compound containing the saccharide. [Solution] The present invention provides a met

Design, synthesis and cytotoxic activity of N-Modified oleanolic saponins bearing A glucosamine

Lin, You-Yu,Chan, She-Hung,Juang, Yu-Pu,Hsiao, Hsin-Min,Guh, Jih-Hwa,Liang, Pi-Hui

, p. 1942 - 1958 (2017/11/16)

A series of N-acyl, N-alkoxycarbonyl, and N-alkylcarbamoyl derivatives of 2′-deoxy-glucosyl bearing oleanolic saponins were synthesized and evaluated against HL-60, PC-3, and HT29 tumor cancer cells. The SAR studies revealed that the activity increased in order of conjugation of 2′ -amino group with carbamate > amide > urea derivatives. Lengthening the alkyl chain increased the cytotoxicity, the peak activity was found to around heptyl to nonyl substitutions. 2′-N-heptoxycarbonyl derivative 56 was found to be the most cytotoxic (IC50 = 0.76 μM) against HL-60 cells. Due to the interesting SARs of alkyl substitutions, we hypothesized that their location in the cell was different, and pursued a location study using 2′-(4″-pentynoylamino) 2′-deoxy-glucosyl OA, which suggested that these compounds distributed mainly in the cytosol.

Cu(ClO4)2·6H2O catalyzed solvent free per-O-acetylation and sequential one-pot conversions of sugars to thioglycosides

Chatterjee, Debnath,Paul, Abhijit,Rajkamal,Yadav, Somnath

, p. 29669 - 29674 (2015/05/20)

The solvent free per-O-acetylation of various reducing and non-reducing sugars has been carried out using stoichiometric amounts of acetic anhydride and copper(ii) perchlorate hexahydrate as the catalyst. The reactions with various reducing monosaccharides have also been followed by a one-pot sequential conversion to the corresponding thioglycosides in high yields. This journal is
