(2R,4'R,8'R)-α-tocopheramine, also known as alpha-tocopherol, is a naturally occurring form of vitamin E, a fat-soluble antioxidant that plays a crucial role in protecting cells from oxidative damage. It is characterized by its chiral centers at the 2nd, 4'th, and 8'th positions, which give it the specific (2R,4'R,8'R) configuration. This form of vitamin E is the most biologically active and is essential for maintaining healthy cell membranes, supporting the immune system, and preventing degenerative diseases. It is primarily found in vegetable oils, nuts, and seeds, and is also available as a dietary supplement.
The CAS Registry Mumber 3398-70-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,3,9 and 8 respectively; the second part has 2 digits, 7 and 0 respectively. Calculate Digit Verification of CAS Registry Number 3398-70: (6*3)+(5*3)+(4*9)+(3*8)+(2*7)+(1*0)=107 107 % 10 = 7 So 3398-70-7 is a valid CAS Registry Number.
