1421611-55-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1421611-55-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,1,6,1 and 1 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1421611-55:
(9*1)+(8*4)+(7*2)+(6*1)+(5*6)+(4*1)+(3*1)+(2*5)+(1*5)=113
113 % 10 = 3
So 1421611-55-3 is a valid CAS Registry Number.

Alkoxyamino glycoside acceptors for the regioselective synthesis of oligosaccharides using glycosynthases and transglycosidases

Teze, David,Dion, Michel,Daligault, Franck,Tran, Vinh,Andre-Miral, Corinne,Tellier, Charles

supporting information, p. 448 - 451 (2013/02/23)

Alkoxyamino derivatives of oligosaccharides have been synthesized by enzymatic synthesis using a glycosynthase and a transglycosidase. The chemoselective assembly of unprotected oligosaccharides bearing glucose at the reducing end with N-alkyl-O-benzylhydroxylamine provides sugar derivatives that are good acceptors for enzymatic synthesis using either glycosynthase or transglycosidase. Furthermore, this method affords the possibility of controlling the regioselectivity of coupling depending on the nature of the alkoxyamino substituent and provides high-yield coupling of sugars without the need for complex protecting group chemistry.
