It crystallises from EtOH/H2O (1:1). It precipitates as the hydrochloride with dilute HCl which has m 282o. [Dasgupta et al. Anal Chim Acta 94 205 1977, Beilstein 24 H 193, 25 III/IV 2677.]
Check Digit Verification of cas no
The CAS Registry Mumber 28832-64-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,8,3 and 2 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 28832-64:
(7*2)+(6*8)+(5*8)+(4*3)+(3*2)+(2*6)+(1*4)=136
136 % 10 = 6
So 28832-64-6 is a valid CAS Registry Number.

13C and 1H NMR Studies of Structure and Tautomerism in Some Perimidines
Woodgate, P. D.,Herbert, J. M.,Denny, W. A.
, p. 191 - 196 (2007/10/02)
The 13C NMR spectra of some 1- and 2-substituted perimidines and perimidinium salts are discussed and assigned.Although the spectra of most of the 2-substituted perimidines are comparatively simple, several examples display 13C and 1H spectral characteristics indicative of inhibition of prototropic tautomerism.KEY WORDS 13C NMR Perimidines Perimidinium salts 1H NMR Tautomerism
