Check Digit Verification of cas no

The CAS Registry Mumber 1247-97-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,4 and 7 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1247-97:
(6*1)+(5*2)+(4*4)+(3*7)+(2*9)+(1*7)=78
78 % 10 = 8
So 1247-97-8 is a valid CAS Registry Number.

O-ALKYLATION DE LA QUERCETINE ET SYNTHESE DE LA TETRA-O-EHYL-3,7,3',4' O-ETHYL -5 QUERCETINE

Picq, M.,Prigent, A. F.,Chabannes, B.,Pacheco, H.,Parent, P.,Pichat, L.

, p. 2227 - 2230 (1984)

An efficient procedure is described for alkylation of quercetin with alkyl halides by use of tetraethylammonium fluoride in DMF or HMPT.The method is applied successfully to the preparation of 3,7,3',4', tetra-O-ethyl 5 O-ethylquercetin with a specific radioactivity of 45 Ci/mmol.

A flavonol glycoside-lignan ester and accompanying acylated glucosides from Monochaetum multiflorum

Isaza, Jose H,Ito, Hideyuki,Yoshida, Takashi

, p. 321 - 327 (2001)

Four acylated glycosides along with six known glycosides were isolated from the leaves of Monochaetum multiflorum. The new compounds were characterized as 4.0-(6′-O-galloyl- β- glucopyranosyl)-cis-p-coumaric acid, 6′-O- galloylprunasin, benzyl 6′-O-galloyl-β-glucopyranoside, and a novel diester of tetrahydroxy-μ-truxinic acid with 2 mol of hyperin (monochaetin), based on NMR and MS spectral data and chemical evidence.

Method of producing an alkoxyflavone derivative

Page/Page column 6, (2021/01/20)

A method of producing an alkoxyflavone derivative involves a step of reacting hydroxyflavone derivative which is shown in the below chemical formula and dialkyl sulfate in the presence of dimethyl sulfoxide and an alkali hydroxide. Further, in the chemical formula below, R11-R14, R21-R25 and R3 are independently one of hydrogen, hydroxyl group, ester group, alkoxy group, alkylenedioxy group, sulfonyl group and alkyl group, respectively. However, at least two of R21-R25 and R3 are hydroxyl groups.

Unraveling the anti-influenza effect of flavonoids: Experimental validation of luteolin and its congeners as potent influenza endonuclease inhibitors

The biological effects of flavonoids on mammal cells are diverse, ranging from scavenging free radicals and anti-cancer activity to anti-influenza activity. Despite appreciable effort to understand the anti-influenza activity of flavonoids, there is no clear consensus about their precise mode-of-action at a cellular level. Here, we report the development and validation of a screening assay based on AlphaScreen technology and illustrate its application for determination of the inhibitory potency of a large set of polyols against PA N-terminal domain (PA-Nter) of influenza RNA-dependent RNA polymerase featuring endonuclease activity. The most potent inhibitors we identified were luteolin with an IC50 of 72 ± 2 nM and its 8-C-glucoside orientin with an IC50 of 43 ± 2 nM. Submicromolar inhibitors were also evaluated by an in vitro endonuclease activity assay using single-stranded DNA, and the results were in full agreement with data from the competitive AlphaScreen assay. Using X-ray crystallography, we analyzed structures of the PA-Nter in complex with luteolin at 2.0 ? resolution and quambalarine B at 2.5 ? resolution, which clearly revealed the binding pose of these polyols coordinated to two manganese ions in the endonuclease active site. Using two distinct assays along with the structural work, we have presumably identified and characterized the molecular mode-of-action of flavonoids in influenza-infected cells.

A simple and effective preparation of quercetin pentamethyl ether from quercetin

Tatsuzaki, Jin,Ohwada, Tomohiko,Otani, Yuko,Inagi, Reiko,Ishikawa, Tsutomu

supporting information, p. 3112 - 3121 (2019/01/21)

Among the five hydroxy (OH) groups of quercetin (3,5,7,3',4'-pentahydroxyflavone), the OH group at 5 position is the most resistant to methylation due to its strong intramolecular hydrogen bonding with the carbonyl group at 4 position. Thus, it is generally difficult to synthesize the pentamethyl ether efficiently by conventional methylation. Here, we describe a simple and effective perO-methylation of quercetin with dimethyl sulfate in potassium (or sodium) hydroxide/dimethyl sulfoxide at room temperature for about 2 hours, affording quercetin pentamethyl ether (QPE) quantitatively as a single product. When methyl iodide was used in place of dimethyl sulfate, the C-methylation product 6-methylquercetin pentamethyl ether was also formed. A computational study provided a rationale for the experimental results.
