Tyr(Bzl)-D-Ala-Gly-Phe-Leu-OBzl trifluoroacetate is a complex chemical compound consisting of a peptide sequence with a tyrosine residue (Tyr), a benzyl group (Bzl), D-alanine (D-Ala), glycine (Gly), phenylalanine (Phe), and leucine (Leu), all connected in that order. The OBzl at the end indicates that the peptide is capped with a benzyl group. The trifluoroacetate (TFA) is a counterion that helps to stabilize the compound in solution. This specific peptide sequence is often used in the synthesis of larger peptides or as a building block in medicinal chemistry, particularly in the development of antibiotics and other therapeutic agents. The presence of the D-alanine, an unnatural amino acid, and the benzyl protecting groups suggests that Tyr(Bzl)-D-Ala-Gly-Phe-Leu-OBzl trifluoroacetate is designed for specific chemical reactions or to mimic natural peptide structures with enhanced stability or altered biological activity.
The CAS Registry Mumber 99795-29-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,7,9 and 5 respectively; the second part has 2 digits, 2 and 9 respectively. Calculate Digit Verification of CAS Registry Number 99795-29: (7*9)+(6*9)+(5*7)+(4*9)+(3*5)+(2*2)+(1*9)=216 216 % 10 = 6 So 99795-29-6 is a valid CAS Registry Number.
