109140-20-7 Usage
General Description
5-Methoxy-3-chromanone is a lesser-known chemical compound that belongs to the class of organic compounds known as chromones. Chromones are compounds containing a benzopyran (a specific type of six-membered heterocyclic compound) ring system with a ketone at the 2-position (thus forming a chromone moiety) and a methoxy group at the 5-position. 5-Methoxy-3-chromanone is not commonly found or studied, which indicates limited information on its characteristics. However, chromones are known to possess antioxidant and anti-inflammatory properties and are used in various medicinal applications. Its specific physical properties, toxicology or environmental impacts are largely unreported.
Check Digit Verification of cas no
The CAS Registry Mumber 109140-20-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,1,4 and 0 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 109140-20:
(8*1)+(7*0)+(6*9)+(5*1)+(4*4)+(3*0)+(2*2)+(1*0)=87
87 % 10 = 7
So 109140-20-7 is a valid CAS Registry Number.

Rapid access to chroman-3-ones through gold-catalyzed oxidation of propargyl aryl ethers
Wang, Yanzhao,Ji, Kegong,Lan, Sylvester,Zhang, Liming
supporting information; experimental part, p. 1915 - 1918 (2012/03/26)
The two-step: Chroman-3-ones are important intermediates for organic synthesis and medicinal chemistry. However, their syntheses require multiple steps and are not efficient. By using gold-catalyzed alkyne oxidation, this versatile heterocycle can be prepared in only two steps from readily available phenols and with mostly high efficiencies (see scheme).
