33400-78-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 33400-78-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,4,0 and 0 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 33400-78:
(7*3)+(6*3)+(5*4)+(4*0)+(3*0)+(2*7)+(1*8)=81
81 % 10 = 1
So 33400-78-1 is a valid CAS Registry Number.

TAUTOMERS OF AZINE DERIVATIVES. 21. TAUTOMERISM IN 2-(2-HYDROXYARYL)AZINES
Stekhova, S. A.,Lapachev, V. V.,Mamaev, V. P.
, p. 65 - 70 (2007/10/02)
Tautomerism in 2-(2-hydroxyaryl)azines has been studied using 17O NMR and UV spectroscopy.Consideration has been given to the influence of solvent and structural factors which facilitate the establishment of a tautomeric equilibrium in these compounds.
