"Tyr(Bzl)-Lys(Z)-OBzl" is a tripeptide, a chain of three amino acids, with specific protecting groups. Tyrosine (Tyr) is N-benzylated (Bzl), which means its amino group is protected by a benzyl group. Lysine (Lys) is N-benzyloxycarbonyl-protected (Z), indicating its amino group is shielded by a benzyloxycarbonyl group. The terminal amino acid is again tyrosine, but this time it is O-benzylated (OBzl), meaning its hydroxyl group is protected by a benzyl group. This specific sequence and protection scheme are crucial for its stability and reactivity in chemical synthesis, particularly in the context of peptide chemistry where such protecting groups are used to control the order of peptide bond formation and prevent unwanted side reactions.

Check Digit Verification of cas no

The CAS Registry Mumber 79590-59-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,5,9 and 0 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 79590-59:
(7*7)+(6*9)+(5*5)+(4*9)+(3*0)+(2*5)+(1*9)=183
183 % 10 = 3
So 79590-59-3 is a valid CAS Registry Number.

Solution-phase automated synthesis of tripeptide derivatives

Kuroda,Hattori,Kitada,Sugawara

, p. 1138 - 1146 (2007/10/03)

An improved general method for automated synthesis of tripeptides was developed, in which methanesulfonic acid (MSA) was used in place of trifluoroacetic acid (TFA), thus making it possible to avoid, 1) corrosion of the apparatus by strong acid vapor, 2) formation of emulsions, and 3) use of the restricted solvent, dichloromethane. As an application of the automated synthesis apparatus, 216 fragment tripeptide derivatives were synthesized systematically using the MSA method, in excellent yield and with increased efficiency.
