1'-Hydroxy-1',2',7,8-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 photosynthetic organisms. This specific compound is a derivative of the more common carotenoid, lycopene, and is characterized by the presence of a hydroxyl group (-OH) at the 1' position and the saturation of four carbon-carbon double bonds, resulting in a tetrahydro structure. The ψ,ψ notation indicates that the compound has a specific geometric isomerism, which can influence its biological activity and properties. Carotenoids like 1'-Hydroxy-1',2',7,8-tetrahydro-ψ,ψ-carotene are known for their antioxidant properties and potential roles in human health, such as supporting eye health and immune function. They are also used as natural colorants in the food industry.
The CAS Registry Mumber 2104-74-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,0 and 4 respectively; the second part has 2 digits, 7 and 4 respectively. Calculate Digit Verification of CAS Registry Number 2104-74: (6*2)+(5*1)+(4*0)+(3*4)+(2*7)+(1*4)=47 47 % 10 = 7 So 2104-74-7 is a valid CAS Registry Number.
