25018-28-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 25018-28-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,0,1 and 8 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 25018-28:
(7*2)+(6*5)+(5*0)+(4*1)+(3*8)+(2*2)+(1*8)=84
84 % 10 = 4
So 25018-28-4 is a valid CAS Registry Number.

Molecular sieves promote stereocontrolled αα-disaccharide formation via direct dimerization of free sugars

Posner, Gary H.,Bull, D. Scott

, p. 6279 - 6282 (1996)

Some commercial molecular sieves promote direct dimerization of free pyranose and furanose sugars stereoselectively into the corresponding α,α-disaccharides.

2-Allylphenyl glycosides as glycosyl donors for sugar coupling

Luo, Shun-Yuan,Tripathi, Ashish,Zulueta, Medel Manuel L.,Hung, Shang-Cheng

, p. 197 - 201 (2012/06/30)

Glycosylations employing 2-allylphenyl glycoside, a new type of stable glycosyl donor, were optimized and explored with a variety of acceptors promoted by ICl/AgOTf. The utility of the protocol was further demonstrated with an efficient synthesis of the disaccharide fragment of bleomycins.

Formation of O-glycosidic linkages from 1-hydroxy sugars by bismuth(III) triflate-catalyzed dehydrative glycosidation

This paper describes the direct formation of various O-glycosidic linkages from 1-hydroxy sugars by bismuth(III) triflate-catalyzed dehydrative glycosidation. The condensation reactions of 1 -hydroxy sugars with some primary alcohols in the presence of on

2-Allyloxyphenyl glycoside as a new and stable type of glycosyl donors

Lee, Jinq-Chyi,Pan, Guan-Rong,Kulkarni, Suvarn S.,Luo, Shun-Yuan,Liao, Chun-Chen,Hung, Shang-Cheng

, p. 1621 - 1624 (2007/10/03)

A high-yielding coupling of a new and stable type of glycosyl donors, namely 2-allyloxyphenyl glycoside, with a variety of alcohols via NIS/TfOH reagent combination as effective activators at room temperature is described here.

Sulfoxide Covalent Catalysis: Application to Glycosidic Bond Formation

Boebel, Timothy A.,Gin, David Y.

, p. 5874 - 5877 (2007/10/03)

A versatile glycosylation reaction is used to establish the process of sulfoxide covalent catalysis. Hemiacetals are activated by benzenesulfonic anhydride and a dialkyl sulfoxide catalyst, nBu2SO, for coupling with various nucleophiles (Nu; se

Synthesis of methyl O-α-D-mannosyl-(1→4)-[(3-O-methyl-α-D-mannosyl) -(1→4)-]n3-O-methyl-α-D-mannosides (n = 0, 1, and 2) via dehydrative glycosylation

, p. 1301 - 1309 (2007/10/03)

Methyl O-α-D-mannopyranosyl-(1→4)-[(3-O-methyl-α-D-mannopyranosyl -(1→4)-]n3-O-methyl-α-D-mannopyra-nosides (n = 0, 1, and 2), the lowest homologs related to the 3-O-methylmannose polysaccharides (MMP) from Mycobacterium smegmatis, were synthesized via dehydrative glycosylation reactions. The reagent systems, composed of p-nitrobenzenesulfonyl chloride, silver trifluoromethanesulfonate, and triethylamine, of p-nitrobenzenesulfonyl chloride, silver trifluoromethanesulfonate, and 1, 8-diazabicyclo[5.4.0]undec-7-ene, and of trimethylsilyl trifuloromethanesulfonate and pyridine were useful.
