7,8,11,12-Tetrahydro-ψ,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 some microorganisms. This specific carotenoid is a derivative of lycopene, a well-known carotenoid found in tomatoes and other red fruits. The name "7,8,11,12-Tetrahydro-ψ,ψ-carotene" indicates that it has four hydrogen atoms added to the molecule (tetrahydro) and two ψ bonds, which are double bonds that have been reduced to single bonds. These modifications can affect the molecule's stability, solubility, and biological activity. Carotenoids like 7,8,11,12-Tetrahydro-ψ,ψ-carotene play a crucial role in photosynthesis by protecting plants from excess light energy and are also known for their antioxidant properties, which can help protect cells from damage caused by free radicals. Additionally, they contribute to the coloration of various fruits and vegetables, which can be an indicator of their nutritional value.
The CAS Registry Mumber 502-63-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,0 and 2 respectively; the second part has 2 digits, 6 and 3 respectively. Calculate Digit Verification of CAS Registry Number 502-63: (5*5)+(4*0)+(3*2)+(2*6)+(1*3)=46 46 % 10 = 6 So 502-63-6 is a valid CAS Registry Number.
