2-Fluor-3-tosyloxy-propionsaeure-amid, also known as 2-fluoro-3-tosyloxypropionamide, is a chemical compound with the molecular formula C10H12FNO4S. It is a derivative of propionic acid, featuring a fluorine atom at the 2-position, a tosyloxy group (tosylate, derived from toluene) at the 3-position, and an amide functional group. 2-Fluor-3-tosyloxy-propionsaeure-amid is of interest in organic chemistry, particularly in the synthesis of pharmaceuticals and other complex molecules, due to its unique reactivity and the potential for selective fluorination reactions. The tosyloxy group serves as a protecting group for the hydroxyl group, which can be removed under certain conditions to reveal the free hydroxyl group, making it a valuable intermediate in the synthesis of various compounds.

Check Digit Verification of cas no

The CAS Registry Mumber 2248-28-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,4 and 8 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 2248-28:
(6*2)+(5*2)+(4*4)+(3*8)+(2*2)+(1*8)=74
74 % 10 = 4
So 2248-28-4 is a valid CAS Registry Number.
