2903-43-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2903-43-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,0 and 3 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 2903-43:
(6*2)+(5*9)+(4*0)+(3*3)+(2*4)+(1*3)=77
77 % 10 = 7
So 2903-43-7 is a valid CAS Registry Number.

Synthetic Approaches to Chlorinated 5-Hydroxy-5-Methyl-2-Furanones

Franzen, Robert,Kronberg, Leif

, p. 10945 - 10958 (2007/10/02)

The syntheses of chlorinated 5-hydroxy-furanones with a mono-, di-, and trichloromethyl group at C-5 are described.The 5-chloromethyl hydroxyfuranones were obtained by chlorination of levulinic acid followed by triethylamine promoted elimination of hydrogen chloride.Hydrolyses of chlorinated 4-cyclopentene-1,3-diones yielded 5-dichloromethyl hydroxyfuranones.The trichloromethyl group was incorporated to maleic anhydride through thermal decomposition of sodium trichloroacetate.
