778561-25-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 778561-25-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,7,8,5,6 and 1 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 778561-25:
(8*7)+(7*7)+(6*8)+(5*5)+(4*6)+(3*1)+(2*2)+(1*5)=214
214 % 10 = 4
So 778561-25-4 is a valid CAS Registry Number.

Anhydroazasugars as key intermediates in the stereocontrolled preparation of azasugars and their ethyl thioglycosides

Fuentes, Jose,Sayago, Francisco J.,Illangua, Jose M.,Gasch, Consolacion,Angulo, Manuel,Pradera, M. Angeles

, p. 603 - 615 (2007/10/03)

Bicyclic azasugar thioglycosides, a new type of azasugar and alkaloid derivative, are stereoselectively prepared from easily available glycosylenamines (D-gluco and L-rhamno configurations), via 1,4-anhydroazasugar derivatives. Polyhydroxylated pyrrolidines (nonreducing pyrrolidine azasugars) are also prepared by reduction with sodium cyanoborohydride of the same 1,4-anhydroazasugars. The stereochemical assignments of the new stereogenic centres are based on NMR experiments, including a study of the interproton distances from quantitative treatment of NOE data and molecular modeling.
