11031-47-3 Usage
General Description
(2R,2'R,6R,6'R)-5,5',18,18'-Tetradehydro-5,5',6,6'-tetrahydro-2,2'-bis[(E)-4-hydroxy-3-methyl-2-butenyl]-β,β-carotene, also known as astaxanthin, is a naturally occurring carotenoid pigment found in various marine organisms such as algae, shrimp, and salmon. It is a powerful antioxidant with potential health benefits, including anti-inflammatory and immune-boosting properties. Astaxanthin is known for its vibrant red color and is commonly used as a natural food dye in the aquaculture and food industries. It is also used in dietary supplements for its potential health-promoting effects, particularly for skin health and eye health. Additionally, astaxanthin has shown promise in the field of cosmetic and skincare products due to its antioxidative and anti-aging properties.
Check Digit Verification of cas no
The CAS Registry Mumber 11031-47-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,1,0,3 and 1 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 11031-47:
(7*1)+(6*1)+(5*0)+(4*3)+(3*1)+(2*4)+(1*7)=43
43 % 10 = 3
So 11031-47-3 is a valid CAS Registry Number.
