20268-51-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 20268-51-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,2,6 and 8 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 20268-51:
(7*2)+(6*0)+(5*2)+(4*6)+(3*8)+(2*5)+(1*1)=83
83 % 10 = 3
So 20268-51-3 is a valid CAS Registry Number.

Characterization of Nitrobenzanthracenes and Nitrodibenzanthracenes

Iversen, Berit,Sydnes, Leiv K.,Greibrokk, Tyge

, p. 837 - 848 (2007/10/02)

Nitration of benzanthracene, dibenzanthracene, and dibenzanthracene, using nitric acid in acetic anhydride, gave mainly isomeric mixtures of corresponding mononitro derivatives.The derivatives were purified by HPLC on silica to a purity of better than 99.5 percent and indentified on the basis of their 1H NMR, MS and UV data.The main isomers were 7- and 12-nitrobenzanthracene, 9-nitrodibenzanthracene, and 5- and 7-nitrodibenzanthracene.
