119408-32-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 119408-32-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,4,0 and 8 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 119408-32:
(8*1)+(7*1)+(6*9)+(5*4)+(4*0)+(3*8)+(2*3)+(1*2)=121
121 % 10 = 1
So 119408-32-1 is a valid CAS Registry Number.

Nonsteroidal Antiinflammatory Agents, 4. Rearrangement Reactions of Heterocycles, 11. Ketenoid Rearrangement and Oxidation of 2-Pyrons to 1,4-Naphthoquinon-5-alkanoic acids

Kappe, Thomas,Wildpanner, Hans

, p. 727 - 738 (2007/10/02)

Fused 2-pyrones 4, obtained by the thermal condensation of ketones 1 with reactive malonates 2, rearrange above 200 deg C to yield condensed dihydroxynaphthalines 5.The latter compounds can be oxidized to give 3-hydroxy-1,4-naphthoquinone-5-alkanoic acids.The reaction of ketone 8 with magic malonates 2 or chlorocarbonyl ketene 9 affords the pyrones 11 in low yields.The 2-pyrones 11 could not be rearranged to 13; a possible explanation for this behaviour is presented. - Keywords: Trichlorophenyl malonates; 2-Pyrone synthesis; Carbonyl ketenes as intermediates; Hydroxy-1,4-naphthoquinone alkanoic acids
