Check Digit Verification of cas no
The CAS Registry Mumber 20521-56-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,5,2 and 1 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 20521-56:
(7*2)+(6*0)+(5*5)+(4*2)+(3*1)+(2*5)+(1*6)=66
66 % 10 = 6
So 20521-56-6 is a valid CAS Registry Number.

Ozonides of Substituted Norbornenes with Exo- and Endo-Positioned Peroxide Bonds
Griesbaum, Karl,Krieger-Beck, Petra,Beck, Johannes
, p. 4005 - 4008 (2007/10/02)
Ozonolyses of three methyl-substituted norbornenes 1a-c on polyethylene gave in each case the corresponding ozonide 2 with an endo-positioned peroxide bridge.From 1b, ozonide 3b with an exo-positioned peroxide bridge was obtained, too.Thermally and photolytically induced decompositions of the ozonides are described.
