Check Digit Verification of cas no
The CAS Registry Mumber 283-80-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,8 and 3 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 283-80:
(5*2)+(4*8)+(3*3)+(2*8)+(1*0)=67
67 % 10 = 7
So 283-80-7 is a valid CAS Registry Number.

Room temperature observation of p-xylylenes by 1H NMR and evidence for diradical intermediates in their oligomerization
Trahanovsky, Walter S.,Lorimor, Steven P.
, p. 1784 - 1794 (2007/10/03)
p-Quinodimethanes (p-QDMs) are reactive molecules that have been invoked as transient intermediates in a number of reactions. Dilute solutions of benzene-based p-QDMs, p-xylylene (1), α-methyl-p-xylylene (10), and 2,5-dimethyl-p-xylylene (11) can be prepared by fluoride-induced elimination of trimethylsilyl acetate from the appropriate precursor. It has been found that these solutions are stable enough to allow these reactive p-QDMs to be observed by 1H NMR spectroscopy at room temperature. For the first time, the 13C NMR spectrum of p-QDM 1 was observed. After several hours at room temperature, these p-QDMs form dimers, trimers, and insoluble oligomers. Formation of trimers provides evidence that p-QDMs 1, 10, and 11 dimerize by a stepwise mechanism involving dimeric diradicals as intermediates.
