21391-99-1 Usage
General Description
α-Calacorene is a sesquiterpene, a class of organic compounds derived from plants, and is commonly found in various essential oils. It is a colorless liquid with a sweet, woody, and floral odor. α-Calacorene has been identified in the essential oils of several plant species, including Calocedrus macrolepis, Alpinia purpurata, and Laggera alata, among others. It has been found to exhibit antimicrobial and anti-inflammatory properties, making it a potential candidate for use in pharmaceutical and cosmetic products. Additionally, α-calacorene has been studied for its potential as an insect repellent and for its role in plant defense mechanisms. Its unique chemical structure and biological activities make it an interesting compound for further research in various fields.
Check Digit Verification of cas no
The CAS Registry Mumber 21391-99-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,3,9 and 1 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 21391-99:
(7*2)+(6*1)+(5*3)+(4*9)+(3*1)+(2*9)+(1*9)=101
101 % 10 = 1
So 21391-99-1 is a valid CAS Registry Number.

Sesquiterpenoid constituents of the liverwort Marsupella aquatica

Nine new amorphane sesquiterpenoids, (+)-7β-hydroxyamorpha-4,11-diene, (-)-9α-hydroxyamorpha-4,7(11)-diene, (-)-3α-hydroxyamorpha-4,7(11)-diene, (-)-3α-acetoxyamorpha-4,7(11)-diene, (-)-amorpha-4,7(11)-dien-3-one, (+)-2,8-epoxyamorpha-4,7(11)-diene, (+)-5,9-epoxyamorpha-3,7(11)-diene, (-)-2α-hydroxyamorpha-4,7(11)-diene and (-)-2β-acetoxyamorpha-4,7(11)-diene, were isolated from the essential oil of the liverwort Marsupella aquatica, collected near Gaschurn/Montafon, Austria. The isolated compounds and their chemical transformations were investigated using enantioselective GC and extensive spectroscopic studies (HRMS, 1H, 13C and 2D NMR). The absolute configuration of most of the isolated compounds were established by conversions to known compounds. In addition, 1H, and 13C NMR data of (-)-myltayl-4-ene are reported for the first time.
