180045-91-4 Usage
Description
Penigequinolone A is a rare fungal metabolite produced by selected Penicillium species. It is isolated as an inseparable mixture with its 19-epimer, penigequinolone B. Limited literature cites penigequinolone A as a pollen growth inhibitor.
Uses
Used in Pharmaceutical Industry:
Penigequinolone A is used as a pollen growth inhibitor for its ability to inhibit pollen growth, which can be beneficial in the development of treatments for allergies and other pollen-related conditions.
Used in Agricultural Industry:
Penigequinolone A is used as a potential tool for controlling pollen production in plants for the purpose of managing plant reproduction and improving crop yields.
Check Digit Verification of cas no
The CAS Registry Mumber 180045-91-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,0,0,4 and 5 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 180045-91:
(8*1)+(7*8)+(6*0)+(5*0)+(4*4)+(3*5)+(2*9)+(1*1)=114
114 % 10 = 4
So 180045-91-4 is a valid CAS Registry Number.

Divergent Total Syntheses of Yaequinolone-Related Natural Products by Late-Stage C-H Olefination
Ces, Sabela Vega,Fernández-Ibá?ez, M. ángeles,Jia, Wen-Liang
, p. 6259 - 6277 (2021)
Divergent total syntheses of 10 yaequinolone-related natural products have been achieved for the first time by late-stage C-H olefination of 3,4-dioxygenated 4-aryl-5-hydroxyquinolin-2(1H)-ones, core structures of this family of natural products. A robust synthetic methodology to construct the core structures has been established, and the C-H olefination reaction has been carried out with synthetically useful yields and high levels of site-selectivity under mild reaction conditions in the presence of a Pd/S,O-ligand catalyst.
