4''-Hydroxywogonin can be used as an antiviral drug screening for COVID-19 therapy.

Check Digit Verification of cas no

The CAS Registry Mumber 57096-02-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,0,9 and 6 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 57096-02:
133 % 10 = 3
So 57096-02-3 is a valid CAS Registry Number.

O-methylation of flavonoids by cell-free extracts of calamondin orange

Brunet, Gunter,Ibrahim, Ragai K.

, p. 741 - 746 (2007/10/02)

Cell-free extracts of calamondin orange (Citrus mitis) catalysed the O-methylation of almost all hydroxyls of a number of flavonoids, indicating the existence in citrus tissues of ortho, meta, para and 3-O-methyltransferases. The latter, hitherto unreported enzyme, catalysed the formation of 3-O-methyl ethers of galangin and quercetin. The stepwise O-methylation of a number of compounds, especially quercetin and quercetagetin, tends to suggest a coordinated sequence of O-methylations on the surface of a multienzyme complex. The methyl acceptor abilities of the flavonoid substrates used are discussed in relation to their hydroxyl substitution patterns and their negative electron density distribution.
