Check Digit Verification of cas no

The CAS Registry Mumber 85249-92-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,2,4 and 9 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 85249-92:
(7*8)+(6*5)+(5*2)+(4*4)+(3*9)+(2*9)+(1*2)=159
159 % 10 = 9
So 85249-92-9 is a valid CAS Registry Number.

N.M.R. STUDIES OF D-RIBOSYLAMINES IN SOLUTION: DERIVATIVES OF PRIMARY AMINES

Chavis, Claude,Gourcy, Chantal De,Dumont, Francoise,Imbach, Jean-Louis

, p. 1 - 20 (2007/10/02)

N.m.r. spectroscopy (1H, 13C) has been used to show that primary amines condense with D-ribose to give mainly D-ribopyranosylamines in which the α anomer in the 1C4 conformation preponderates; the β anomer assumes mainly the 4C1 conformation.Thus, it is possible to deduce the structures of N-phenyl-D-ribosylamines and to correlate some of the literature data.For 2,3-O-isopropylidene-D-ribofuranosylamine derivatives, the Δδ values for 13C-n.m.r. signals of the isopropylidene methyl groups can be used to establish the anomeric configuration.
