186047-23-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 186047-23-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,6,0,4 and 7 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 186047-23:
(8*1)+(7*8)+(6*6)+(5*0)+(4*4)+(3*7)+(2*2)+(1*3)=144
144 % 10 = 4
So 186047-23-4 is a valid CAS Registry Number.

SUBSTITUENT EFFECTS IN KETO-ENOL TAUTOMERISM. PART 3. INFLUENCE OF SUBSTITUTION ON THE EQUILIBRIUM COMPOSITION OF β-DICARBONYL COMPOUNDS.

Bassetti, M.,Cerichelli, G.,Floris, B.

, p. 2997 - 3004 (1988)

The enol content and equilibrium free energies for the keto-enol tautomerism have been determined for a series of 1,3-diketones, at 40 deg C, in deuterochloroform and dimethylsulfoxide-d6 (DMSO), by (1)H n.m.r..Compounds containing methyl, phenyl, t-butyl, 2-thienyl, trifluoromethyl and ethoxy groups have been examined.The equilibrium free energies in DMSO are characterized by a linear additivity effect, and substituent parameters, representing the variation produced by the substituent, have been calculated.Equilibrium enthalpy and entropy have been obtained in the range of temperature 20-60 deg C.A correlation between enolic 1J-CH= coupling constants and equilibrium free energies in DMSO is discussed in terms of substituent effects on the energy of the enol.

Significant enhancement in radical-scavenging activity of curcuminoids conferred by acetoxy substituent at the central methylene carbon

Kim, Mi Kyoung,Jeong, Wooseong,Kang, Jihoon,Chong, Youhoon

experimental part, p. 3793 - 3800 (2011/08/06)

For a compound to be a radical-trapping antioxidant, the antioxidant-derived radical must be sufficiently inert to molecular oxygen as this would generate harmful chain-propagating peroxyl radicals. Curcumin has a unique structure with phenolic hydroxyl g
