4-Methoxy-2(5H)-furanone is a furanone. 4-Methoxy-2(5H)-furanone is isolated from Narthecium asiaticum maxim leave samples and is reported to cause nephrotoxicity in cattle.

Check Digit Verification of cas no

The CAS Registry Mumber 69556-70-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,5,5 and 6 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 69556-70:
(7*6)+(6*9)+(5*5)+(4*5)+(3*6)+(2*7)+(1*0)=173
173 % 10 = 3
So 69556-70-3 is a valid CAS Registry Number.

Lewis Acid Mediated Addition of Indoles and Alcohols to Tetronic Acid and Tetramic Acids

Banales Mejia, Fernando,Lafferty, Megan M.,Melvin, Sophia J.,Truax, Nathanyal J.,Kean, Maeve H.,Pelkey, Erin T.

, p. 260 - 264 (2017)

The electrophilic substitution of indoles with tetronic acid and N-acetyltetramic acid mediated by BF3·OEt2 was investigated. This strategy allowed for the preparation of nine indole-substituted furan-2-ones (indolyl-γ-lactones) and 3-pyrrolin-2-ones (indolyl-γ-lactams) and is more straightforward than previously reported synthetic methods. During the course of our investigation, we also discovered a facile synthesis of tetronates and a tetramate via a BF3-mediated addition of alcohols to tetronic acid and N-acetyltetramic acid, respectively.
