Check Digit Verification of cas no

The CAS Registry Mumber 85220-34-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,2,2 and 0 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 85220-34:
(7*8)+(6*5)+(5*2)+(4*2)+(3*0)+(2*3)+(1*4)=114
114 % 10 = 4
So 85220-34-4 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.
