Trihydroxy-methyl-[1,4]benzoquinone, also known as vitamin E, is a fat-soluble antioxidant that plays a crucial role in protecting cells from the damage caused by free radicals. It is a group of eight related compounds, including tocopherols and tocotrienols, which are essential for maintaining healthy skin, eyes, and immune system. This chemical is widely found in various plant-based foods, such as nuts, seeds, and vegetable oils, and is also available as a dietary supplement. Its primary function is to neutralize free radicals, thereby preventing oxidative stress and reducing the risk of chronic diseases. Additionally, vitamin E contributes to the proper functioning of the nervous system and supports the overall health and well-being of an individual.

Check Digit Verification of cas no

The CAS Registry Mumber 91808-98-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,8,0 and 8 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 91808-98:
(7*9)+(6*1)+(5*8)+(4*0)+(3*8)+(2*9)+(1*8)=159
159 % 10 = 9
So 91808-98-9 is a valid CAS Registry Number.
