Check Digit Verification of cas no

The CAS Registry Mumber 20633-67-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,6,3 and 3 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 20633-67:
84 % 10 = 4
So 20633-67-4 is a valid CAS Registry Number.

Identification of a flavonoid 7-O-glucosyltransferase from Andrographis paniculata

Li, Yuan,Gao, Wei,Huang, Lu-Qi

, p. 279 - 286 (2019/11/21)

Andrographis paniculata is an important traditional medicinal herb in which flavonoids are part of the primary specialized metabolites. A flavonoid glucosyltransferase with broad substrate spectrum (named ApUGT3) was successfully identified by screening homologous glycosyltransferase genes from A. paniculata. The enzyme displayed glycosylation activity toward multiple flavonoids in?vitro, and the major products were identified as 7-O-glucosides. Phylogenetic analysis revealed that ApUGT3 is the first reported glycosyltransferase from the Acanthaceae family that belongs to cluster I, suggesting that ApUGT3 is a new flavonoid glycosyltransferase of this subcluster. This enzyme is potentially useful as powerful glycosylation catalysts to modify flavonoid-like compounds and improve their biological activities. (Figure presented.).

A method of chemical synthesis mao Ruiyi flavonoid (by machine translation)


, (2017/07/21)

The invention relates to a method for preparing mao Ruiyi flavonoid, comprises the following steps: to resorcinol and 3 - hydroxy -4 - methoxy acetic acid (as the starting material, to make the 3 ', 7 - dihydroxy -4' - methoxyisoflavone, then through the acetylation reaction to obtain the double-b acylated product 3 ', 7 - acetoxy -4' - methoxyisoflavone; selective shall get rid of the 7 bit on the hydroxy protecting group and gets the 7 - hydroxy -3 '- acetoxy -4' - methoxyisoflavone; the 7 position hydroxy generating glycosidic bond to obtain 3 '- acetoxy -4' - methoxyisoflavone - 7 - O - beta - D - tetra-substituted-based glucoside, finally through complete hydrolysis, removing the protecting group to obtain mao Ruiyi flavonoid, namely calycosin - 7 - O - beta - D - glucoside. The invention develops mao Ruiyi flavonoid glycoside of chemical synthesis method, this synthetic route raw materials are easy, and the cost is low, mild reaction conditions.
