2,2'-Bifuran-3-carboxylic acid methyl ester is an organic compound with the chemical formula C8H8O4. It is a derivative of furan, a heterocyclic aromatic organic compound consisting of a five-membered ring with four carbon atoms and one oxygen atom. In this specific compound, two furan rings are connected through a methylene bridge (-CH2-), and a carboxylic acid group (-COOH) is present on the third carbon of each furan ring. The carboxylic acid group on one of the furan rings is esterified with a methyl group (-CH3), resulting in the formation of a methyl ester (-COOCH3). 2,2'-Bifuran-3-carboxylic acid methyl ester is known for its potential applications in the synthesis of various pharmaceuticals and agrochemicals, as well as its use as an intermediate in the preparation of other organic compounds.

Check Digit Verification of cas no

The CAS Registry Mumber 5905-07-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,9,0 and 5 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 5905-07:
(6*5)+(5*9)+(4*0)+(3*5)+(2*0)+(1*7)=97
97 % 10 = 7
So 5905-07-7 is a valid CAS Registry Number.

Diethylene Glycol Serving as Ethyne Equivalent: A Sustainable Approach toward 2,3-Disubstituted Furan

Yu, Jin-Tao,Shi, Bo,Peng, Haibo,Sun, Song,Chu, Haoke,Jiang, Yan,Cheng, Jiang

supporting information, p. 3643 - 3645 (2015/08/18)

In the presence of tert-butyl peroxide (TBHP), the copper-catalyzed annulation of 1,3-dicarbonyl compound with diethylene glycol was developed leading to 2,3-disubstituted furan. Diethylene glycol serves as a cheap and environmentally friendly equivalent of ethyne, with the release of H2O and alcohol as clean wastes. The procedure involves a sequential O- and C- functionalization of β-ketoester by diethylene glycol.
