Check Digit Verification of cas no

The CAS Registry Mumber 4163-60-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,1,6 and 3 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4163-60:
(6*4)+(5*1)+(4*6)+(3*3)+(2*6)+(1*0)=74
74 % 10 = 4
So 4163-60-4 is a valid CAS Registry Number.

Assembly, postsynthetic modification and hepatocyte targeting by multiantennary, galactosylated soft structures

Thomas, Anisha,Shukla, Akansha,Sivakumar, Sri,Verma, Sandeep

, p. 15752 - 15755 (2014)

Enzyme modifiable, hollow self-assembled structures offer an excellent scope for multiantennary delivery vectors. Herein, we report synthesis and applications of bis-galactose lysine based supramolecular ensembles, which possess surface galactose moieties

Size-optimized galactose-capped gold nanoparticles for the colorimetric detection of heat-labile enterotoxin at nanomolar concentrations

Poonthiyil, Vivek,Golovko, Vladimir B.,Fairbanks, Antony J.

, p. 5215 - 5223 (2015)

The development of a galactose-capped gold nanoparticle-based colorimetric sensor for the detection of the lectin heat-labile enterotoxin is reported. Heat-labile enterotoxin is one of the pathogenic agents responsible for the intestinal disease called 'traveller's diarrhoea'. By means of specific interaction between galactose moieties attached to the surface of gold nanoparticles and receptors on the B-subunit of heat-labile enterotoxin (LTB), the gold nanoparticles reported here act as an efficient colorimetric sensor, which can detect the toxin at nanomolar concentrations. The effect of gold nanoparticle size on the detection sensitivity was investigated in detail. Amongst the various sizes of gold nanoparticles studied (2, 7, 12, and 20 nm), the 12 nm sized gold nanoparticles were found to be the most efficient, with a minimum heat-labile enterotoxin detection concentration of 100 nM. The red to purple colour change of the gold nanoparticle solution occurred within two minutes, indicating rapid toxin sensing. This journal is

Synthesis, anticancer activity and cytotoxicity of 7-O-β-d-galactosyl-polyethylene glycol-epothilone B

Huang, Shiyu,Huang, Gangliang

, p. 539 - 543 (2019)

Epothilone, the macrolide compound produced by Sorangium cellulosum, has antitumor activity. Its anti-tumor mechanism is similar to that of paclitaxel, which promotes the polymerization of tubulin and induces apoptosis. Herein, 7-O-β-d-galactosyl-polyethy

Selectivity of 1-O-Propargyl-D-Mannose Preparations

?ezanka, Michal,Dolensky, Bohumil,Krabicová, Ilona

, (2022/03/01)

Thanks to their ability to bind to specific biological receptors, mannosylated structures are examined in biomedical applications. One of the most common ways of linking a functional moiety to a structure is to use an azide-alkyne click reaction. Therefore, it is necessary to prepare and isolate a propargylated mannose derivative of high purity to maintain its bioactivity. Three known preparations of propargyl-α-mannopyranoside were revisited, and products were analysed by NMR spectroscopy. The preparations were shown to yield by-products that have not been described in the literature yet. Our experiments showed that one-step procedures could not provide pure propargyl-α-mannopyranoside, while a three-step procedure yielded the desired compound of high purity.

Page/Page column 11; 12, (2022/02/28)

The present invention relates to a synthesis process of β-6-sulfoquinovosyl-diacylglycerols. In particular, said process is for the synthesis of the compounds 1,2-O-distearoyl-3-O-(β- sulfoquinovosyl)-R/S-glycerol, 1,2-O-distearoyl-3-O-(β-sulfoquinovosyl)-R-glycerol or 1,2- O-distearoyl-3-O-(β-sulfoquinovosyl)-S-glycerol, named respectively Sulfavant A, Sulfavant R and Sulfavant S.

New amphiphilic platinum(II) phthalocyanine with peracetylated β-galactose moiety – Synthesis and photophysical properties

Burtsev, Ivan D.,Volov, Alexander N.,Volov, Nikolai A.

, (2021/06/28)

The synthesis of new glycoconjugated phthalonitrile connected with galactose moiety by triazole spacer via Cu(II)-mediated click reaction is reported. Reaction of azido derivatives of. β-D-galactopyranose tetraacetate with 4-O-propargyloxy-substituted phthalonitrile in presence copper(II) sulfate pentahydrate and sodium L-ascorbate in tert-butanol/water gave desired glycophthalonitrile with 79% yield. Obtained phthalonitrile underwent mixed-cyclisation with the 4-tert-butyl-substituted phthalonitrile, to afford the mono-glycosylated platinum(II) phthalocyanine. Upon irradiation these compounds could sensitise the formation of singlet oxygen in acetone, with 0.90 quantum yield by method with use of 1,3-diphenylisobenzofuran (DPBF) as scavenger.
