6299-05-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6299-05-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,2,9 and 9 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 6299-05:
(6*6)+(5*2)+(4*9)+(3*9)+(2*0)+(1*5)=114
114 % 10 = 4
So 6299-05-4 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

Manny, Anthony J.,Kjelleberg, Staffan,Kumar, Naresh,De Nys, Rocky,Read, Roger W.,Steinberg, Peter

, p. 15813 - 15826 (2007/10/03)

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.
