N2-trifluoroacetyl-L-asparagine ethyl ester is a chemical compound with the molecular formula C8H11F3N2O4. It is a derivative of L-asparagine, an amino acid, where the N2 position is acylated with a trifluoroacetyl group, and the carboxylic acid group is esterified with an ethyl group. N²-trifluoroacetyl-L-asparagine ethyl ester is often used in organic synthesis and as an intermediate in the preparation of various pharmaceuticals and bioactive molecules. Its structure features a central amide bond, with the trifluoroacetyl group enhancing the reactivity and stability of the molecule, while the ethyl ester group can be hydrolyzed under certain conditions to release the free carboxylic acid. The compound's properties, such as its solubility and reactivity, make it a valuable tool in the synthesis of complex organic molecules, particularly in the field of medicinal chemistry.

Check Digit Verification of cas no

The CAS Registry Mumber 687-29-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,8 and 7 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 687-29:
(5*6)+(4*8)+(3*7)+(2*2)+(1*9)=96
96 % 10 = 6
So 687-29-6 is a valid CAS Registry Number.
