Check Digit Verification of cas no

The CAS Registry Mumber 1353742-17-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,3,7,4 and 2 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1353742-17:
(9*1)+(8*3)+(7*5)+(6*3)+(5*7)+(4*4)+(3*2)+(2*1)+(1*7)=152
152 % 10 = 2
So 1353742-17-2 is a valid CAS Registry Number.

N-O bond as a glycosidic-bond surrogate: Synthetic studies toward polyhydroxylated N-alkoxypiperidines

Malik, Ga?lle,Ferry, Angélique,Guinchard, Xavier,Cresteil, Thierry,Crich, David

, p. 2168 - 2179 (2013/03/29)

A series of novel polyhydroxylated N-alkoxypiperidines has been synthesized by ring-closing double reductive amination (DRA) of highly functionalized 1,5-dialdehydes with various hydroxylamines. The required saccharide-based dialdehydes were prepared efficiently from sodium cyclopentadienylide in seven steps. A two-step protocol has been developed for the DRA; it led, after deprotection, to isofagomine, 3-deoxyisofagomine, and numerous other N-alkoxy analogues. The barrier to inversion in these polyhydroxylated N-alkoxypiperidine derivatives was found by variable-temperature NMR methods to be approximately 15 kcal mol-1. With the exception of N-hydroxyisofagomine itself, none of the compounds prepared showed significant inhibitory activity against sweet almond β-glucosidase. Copyright
