72536-33-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 72536-33-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,5,3 and 6 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 72536-33:
(7*7)+(6*2)+(5*5)+(4*3)+(3*6)+(2*3)+(1*3)=125
125 % 10 = 5
So 72536-33-5 is a valid CAS Registry Number.

Synthesis and 1H N.M.R. Spectroscopic Analysis of Some 3,7-Dioxabicyclooctane Lignans

Velde, Vincent Vande,Lavie, David,Gottlieb, Hugo E.,Perold, Guido W.,Scheinmann, Feodor

, p. 1159 - 1164 (2007/10/02)

Within the framework of a synthetic project towards the preparation of the natural germination inhibitor 2,6-diaryl-3,7-dioxabicyclooctane, several molecules with the same bicyclic skeleton were prepared and their 1H n.m.r. spectra are described in detail.For the symmetrical systems particularly, the spectra exhibited second-order features and were interpreted analytically or, when necessary, by computer simulation.These n.m.r. data enabled a conformational analysis of the ring system.
