(+/-)-cis-4'-acetylkhellactone is a naturally occurring chemical compound derived from the khellactone family, which is found in the seeds of the khella plant (Ammi visnaga). (+/-)-cis-4'-acetylkhellactone exhibits a unique structure, featuring a furan ring and an acetylated coumarin moiety. It is known for its potential biological activities, such as anti-inflammatory and vasodilatory effects, which have been studied for their possible applications in the treatment of various conditions, including respiratory diseases and cardiovascular issues. The (+/-)-cis-4'-acetylkhellactone is a racemic mixture, meaning it contains both the R and S enantiomers, which may have different biological activities. Research on (+/-)-cis-4'-acetylkhellactone and its derivatives continues to explore their potential therapeutic uses and mechanisms of action.

4955-21-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4955-21-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,5 and 5 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 4955-21:
(6*4)+(5*9)+(4*5)+(3*5)+(2*2)+(1*1)=109
109 % 10 = 9
So 4955-21-9 is a valid CAS Registry Number.
