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.

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

Yamanoi, Takashi,Inoue, Ryo,Matsuda, Sho,Iwao, Kazuya,Oda, Yoshiki,Yoshida, Akihiro,Hamasaki, Keita

experimental part, p. 445 - 460 (2009/09/30)

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

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
