Check Digit Verification of cas no
The CAS Registry Mumber 54260-84-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,2,6 and 0 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 54260-84:
(7*5)+(6*4)+(5*2)+(4*6)+(3*0)+(2*8)+(1*4)=113
113 % 10 = 3
So 54260-84-3 is a valid CAS Registry Number.

Reinvestigation of the sulfuric acid-catalysed cyclisation of brominated 2-alkyllevulinic acids to 3-alkyl-5-methylene-2(5H)-furanones

A synthesis of ethyl-, butyl-, hexyl- and dodecyl-substituted fimbrolides from alkyl-substituted levulinic acid derivatives through bromination and acid promoted lactonisation is described. The underlying reactions have been investigated using levulinic acid as a model, and the effects of varying the bromination conditions and changing acid concentration on product distribution are discussed. Dibromination proceeds best in CHCl3 and proceeds in EtOH-free CHCl3 without the complication of ester formation. Cyclisation. occurs with concomitant oxidation in 98-100% H2SO4 but gives highest yields of fimbrolides in 100% H2SO4. The formation of related beckerelide substances is also described.
