Check Digit Verification of cas no

The CAS Registry Mumber 678142-34-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,8,1,4 and 2 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 678142-34:
(8*6)+(7*7)+(6*8)+(5*1)+(4*4)+(3*2)+(2*3)+(1*4)=182
182 % 10 = 2
So 678142-34-2 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.
