34297-68-2 Usage
General Description
3,5-DIMETHYL-FURAN-2-CARBOXYLIC ACID is a chemical compound with the molecular formula C7H8O3. It is a derivative of furan, a heterocyclic compound with a five-membered ring containing four carbon atoms and one oxygen atom. 3,5-DIMETHYL-FURAN-2-CARBOXYLIC ACID is a carboxylic acid, which means it contains a carboxyl group (-COOH) and is capable of donating a hydrogen ion in solution. 3,5-DIMETHYL-FURAN-2-CARBOXYLIC ACID is used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, and it also has applications in the development of materials and in the field of organic chemistry research.
Check Digit Verification of cas no
The CAS Registry Mumber 34297-68-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,2,9 and 7 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 34297-68:
(7*3)+(6*4)+(5*2)+(4*9)+(3*7)+(2*6)+(1*8)=132
132 % 10 = 2
So 34297-68-2 is a valid CAS Registry Number.

The Generation and Chemistry of Dianions derived from Furancarboxylic Acids
Knight, David W.,Nott, Andrew P.
, p. 1125 - 1131 (2007/10/02)
Methods for the generation of the dianionic species lithium 5-lithiofuran-2-carboxylate (5) and lithium 2-lithiofuran-3-carboxylate (21) from furan-2- and furan-3-carboxylic acids recpectively are described.The reactions of (5) and (21) with a range of electrophiles have been examined; in general these are very efficient with aldehydes and ketones but not as satisfactory with alkyl halides and epoxides.The dianions do not couple with allylic or benzylic halides, nor with nitriles or orthoesters.The generation of lithium-5-lithio-3-methylfuran-2-carboxylate (15) from 3-methyl furan-2-carboxylic acid is also described; the chemistry of (15) is very similar to (5) derived from furan-2-carboxylic acid.
