"Z(OMe)-Ser(Bzl)-Ser(Bzl)-OH*DCHA" is a complex chemical compound, representing a peptide sequence with specific modifications. The "Z" group is a protecting group for the amino group, often used in peptide synthesis to prevent unwanted side reactions. "OMe" stands for methoxy, which is part of the Z group. "Ser" is the abbreviation for serine, an amino acid. The "Bzl" group is a benzyl protecting group for the hydroxyl group of serine, which is commonly used in organic synthesis to protect alcohols. The presence of two serine residues with Bzl protecting groups indicates a dipeptide with serine at both positions. "OH" signifies the presence of a hydroxyl group, and "DCHA" likely refers to dicyclohexylamine, a base often used in peptide synthesis to facilitate certain reactions. Z(OMe)-Ser(Bzl)-Ser(Bzl)-OH*DCHA is thus a protected dipeptide with serine at both the N-terminal and C-terminal positions, featuring benzyl protecting groups on the hydroxyl groups of both serine residues, and is associated with dicyclohexylamine, which plays a role in its synthesis or protection strategy.
The CAS Registry Mumber 96935-92-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,6,9,3 and 5 respectively; the second part has 2 digits, 9 and 2 respectively. Calculate Digit Verification of CAS Registry Number 96935-92: (7*9)+(6*6)+(5*9)+(4*3)+(3*5)+(2*9)+(1*2)=191 191 % 10 = 1 So 96935-92-1 is a valid CAS Registry Number.
