4-Propyl-5,7-dihydroxy-6-(3-methyl-2-butenyl)-8-(3-methylbutyryl)-2H-1-benzopyran-2-one is a complex organic compound belonging to the class of flavonoids, specifically a flavanone. This molecule is characterized by a benzopyran-2-one core structure, which is a type of chromone with a benzene ring fused to a pyran ring. The compound features a 4-propyl chain, which is a three-carbon alkyl group attached to the fourth carbon of the benzopyran ring. Additionally, it has two hydroxyl groups at the 5th and 7th positions, contributing to its hydrophilic properties. The 6th position is adorned with a 3-methyl-2-butenyl group, which is a branched-chain alkene, and the 8th position has a 3-methylbutyryl group, a branched-chain ester. 4-Propyl-5,7-dihydroxy-6-(3-methyl-2-butenyl)-8-(3-methylbutyryl)-2H-1-benzopyran-2-one is known for its potential antioxidant and biological activities, which are of interest in the fields of medicine and pharmacology.

Check Digit Verification of cas no

The CAS Registry Mumber 521-38-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,2 and 1 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 521-38:
(5*5)+(4*2)+(3*1)+(2*3)+(1*8)=50
50 % 10 = 0
So 521-38-0 is a valid CAS Registry Number.

Synthesis of Mammea Coumarins. Part 1. The Coumarins of the Mammea A, B, and C Series

Crombie, Leslie,Jones, Raymond C. F.,Palmer, Christopher J.

, p. 317 - 332 (2007/10/02)

The naturally-occuring Mammea coumarins of the 4-phenyl-(mammea A), propyl-(mammea B), and 4-pentyl-(mammea C) series have been prepared by Pechmann condensation of an acylphloroglucinol (3-methylbutyryl-, 2-methylbutyryl-, butyryl-, or 2-methylpropionyl-) with the appropriate β-ketoester to give a mixture of 6- and 8-acyl-5,7-dihydroxycoumarins that could be separated.C-Alkylation with 3-methylbut-2-enyl bromide, or 3,7-dimethylocta-2,6-dienyl chloride, in aqueous potassium hydroxide completed the synthesis of the Mammea coumarins having unmodified prenyl or geranyl substituents; oxidative modification of the prenyl group led to the mammea cyclo E and cyclo F coumarins.Some mammea cyclo D (chromeno) coumarins were synthesized by reaction of acylcoumarins with 1,1-dimethoxy-3-methylbutan-3-ol.
