Zeaxanthin is a naturally occurring carotenoid, a type of organic pigment, that plays a crucial role in the photosynthesis process of plants by protecting them from excessive light. It is also found in the macula of the human eye, where it contributes to maintaining healthy vision and may help protect against age-related macular degeneration. Zeaxanthin is known for its antioxidant properties, which can help neutralize free radicals and reduce oxidative stress. It is commonly found in foods such as green leafy vegetables, corn, and egg yolks, and is also available as a dietary supplement. The chemical structure of zeaxanthin consists of a hydrocarbon chain with multiple conjugated double bonds, which gives it its characteristic yellow color and its ability to absorb light in the blue part of the spectrum.

Check Digit Verification of cas no

The CAS Registry Mumber 472-69-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,7 and 2 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 472-69:
(5*4)+(4*7)+(3*2)+(2*6)+(1*9)=75
75 % 10 = 5
So 472-69-5 is a valid CAS Registry Number.
