Check Digit Verification of cas no
The CAS Registry Mumber 332-82-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,3 and 2 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 332-82:
(5*3)+(4*3)+(3*2)+(2*8)+(1*2)=51
51 % 10 = 1
So 332-82-1 is a valid CAS Registry Number.

Keto-enol and enol-enol tautomerism in trifluoromethyl-β-diketones
Sloop, Joseph C.,Bumgardner, Carl L.,Washington, Gary,Loehle, W. David,Sankar, Sabapathy S.,Lewis, Adam B.
, p. 780 - 786 (2008/03/27)
The keto-enol (K?E) and enol-enol (E?E) equilibria of a variety of trifluoromethyl-β-diketones were investigated using 1H, 13C, 19F NMR spectroscopy, infrared spectroscopy and ultraviolet-visible spectrophotometry in nonpolar solvents. In general, NMR, IR and UV spectral evidence indicates that trifluoromethyl-β-diketones exist as mixtures of two chelated cis-enol forms in nonpolar media. Infrared spectroscopy and ultraviolet spectrophotometry show the E?E equilibrium lies in the direction of the enol form which maximizes conjugation in most cases. Exceptions are noted and discussed.
