Vitamin A α-methyl-α-ethylcapronate, also known as A-MEC, is a synthetic derivative of Vitamin A, specifically a provitamin A ester. It is used as a dietary supplement and in the formulation of various pharmaceuticals due to its enhanced stability and bioavailability compared to other forms of Vitamin A. A-MEC is converted into retinol, the active form of Vitamin A, in the human body, which plays a crucial role in maintaining healthy vision, immune function, and cell growth. The esterification of Vitamin A with α-methyl and α-ethyl groups improves its solubility and stability, making it a preferred form for oral administration and storage.

Check Digit Verification of cas no

The CAS Registry Mumber 20559-06-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,5,5 and 9 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 20559-06:
(7*2)+(6*0)+(5*5)+(4*5)+(3*9)+(2*0)+(1*6)=92
92 % 10 = 2
So 20559-06-2 is a valid CAS Registry Number.
