α-Aminobutyroyl-D-isoglutamine benzyl ester trifluoroacetate is a complex organic compound with the chemical formula C18H26F3N3O5. It is a derivative of amino acids, specifically a combination of α-aminoisobutyric acid (Aib) and D-isoglutamine (D-Ile), with a benzyl ester group and a trifluoroacetic acid (TFA) counterion. α-aminoisobutyroyl-D-isoglutamine benzyl ester trifluoroacetate is often used in peptide synthesis, particularly in the study of peptidomimetics and the development of novel bioactive molecules. The presence of the Aib residue, which is not a natural amino acid, can introduce unique conformational properties to the peptide chain, while the D-Ile provides a chiral center. The benzyl ester group is commonly used to protect the carboxylic acid group during synthesis, and the trifluoroacetic acid is a strong acid often used in peptide synthesis for cleaving protecting groups. The compound's structure and properties make it a valuable tool in medicinal chemistry and drug design.

Check Digit Verification of cas no

The CAS Registry Mumber 71811-17-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,8,1 and 1 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 71811-17:
(7*7)+(6*1)+(5*8)+(4*1)+(3*1)+(2*1)+(1*7)=111
111 % 10 = 1
So 71811-17-1 is a valid CAS Registry Number.
