22854-00-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 22854-00-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,8,5 and 4 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 22854-00:
(7*2)+(6*2)+(5*8)+(4*5)+(3*4)+(2*0)+(1*0)=98
98 % 10 = 8
So 22854-00-8 is a valid CAS Registry Number.

Protecting-group-free one-pot synthesis of glycoconjugates directly from reducing sugars

Lim, David,Brimble, Margaret A.,Kowalczyk, Renata,Watson, Andrew J.A.,Fairbanks, Antony John

, p. 11907 - 11911 (2014)

The conversion of sugars into glycomimetics typically involves multiple protecting-group manipulations. The development of methodology allowing the direct aqueous conversion of free sugars into glycosides, and mimics of oligosaccharides and glycoconjugates in a high-yielding and stereoselective process is highly desirable. The combined use of 2-azido-1,3-dimethylimidazolinium hexafluorophosphate and the Cu-catalyzed Huisgen cycloaddition allowed the synthesis of a range of glycoconjugates in a one-step reaction directly from reducing sugars under aqueous conditions. The reaction, which is completely stereoselective, may be applied to the convergent synthesis of triazole-linked glycosides, oligosaccharides, and glycopeptides. The procedure provides a method for the one-pot aqueous ligation of oligosaccharides and peptides bearing alkyne side chains.
