15,15'-didehydro-β,β-carotene-4,4'-dione, also known as canthaxanthin, is a naturally occurring carotenoid pigment that belongs to the xanthophyll class. It is an important antioxidant and plays a crucial role in various biological processes, including photosynthesis and the protection of cells from oxidative damage. Canthaxanthin is widely found in nature, particularly in algae, crustaceans, and certain fruits and vegetables. It is also used as a food colorant and a dietary supplement, particularly in the aquaculture industry to enhance the color of fish such as salmon. The chemical structure of canthaxanthin features two conjugated double bonds and two carbonyl groups, which contribute to its distinct color and biological activity.

4481-74-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4481-74-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,8 and 1 respectively; the second part has 2 digits, 7 and 4 respectively.Calculate Digit Verification of CAS Registry Number 4481-74:
(6*4)+(5*4)+(4*8)+(3*1)+(2*7)+(1*4)=97
97 % 10 = 7
So 4481-74-7 is a valid CAS Registry Number.
