1'-Hydroxy-1',2'-dihydro-β,ψ-carotene is a naturally occurring carotenoid, which is a class of organic compounds that are responsible for the yellow, orange, and red colors in plants and photosynthetic organisms. This specific compound is a derivative of β-carotene, a well-known carotenoid that serves as a precursor to vitamin A. The molecule features a hydroxyl group (-OH) at the 1' position and a dihydro (reduced) structure at the 1',2' double bond, which distinguishes it from its parent compound. 1'-Hydroxy-1',2'-dihydro-β,ψ-carotene is found in various fruits and vegetables, and it plays a role in the antioxidant defense system, protecting cells from oxidative stress. Its unique structure also contributes to its potential health benefits, although further research is needed to fully understand its biological activities and applications in human health.
The CAS Registry Mumber 2518-26-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,1 and 8 respectively; the second part has 2 digits, 2 and 6 respectively. Calculate Digit Verification of CAS Registry Number 2518-26: (6*2)+(5*5)+(4*1)+(3*8)+(2*2)+(1*6)=75 75 % 10 = 5 So 2518-26-5 is a valid CAS Registry Number.
