Z-Ile-O(TBA), also known as N-benzyloxycarbonyl-L-isoleucine tert-butyl ester, is a chemical compound derived from the amino acid L-isoleucine. It is a protected form of L-isoleucine, where the amino group is capped with a benzyloxycarbonyl (Z) group, and the carboxylic acid group is esterified with a tert-butyl (TBA) group. Z-Ile-O(TBA) is commonly used in peptide synthesis as a building block, allowing for the stepwise assembly of peptide chains while protecting the reactive groups from unwanted side reactions. The Z group is later removed under acidic conditions to expose the free amino group, enabling further peptide bond formation, while the TBA group is cleaved under basic conditions to release the final peptide product.

Check Digit Verification of cas no

The CAS Registry Mumber 77511-17-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,5,1 and 1 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 77511-17:
(7*7)+(6*7)+(5*5)+(4*1)+(3*1)+(2*1)+(1*7)=132
132 % 10 = 2
So 77511-17-2 is a valid CAS Registry Number.
