"Z-Asp(OBut)-Gly-OPh" is a peptide compound consisting of three amino acid residues: Z-protected aspartic acid (Asp), glycine (Gly), and phenylalanine (Ph). The "Z" group is a protecting group used in peptide synthesis to prevent unwanted side reactions, while the "OBut" group is a tert-butyloxycarbonyl (Boc) protecting group attached to the aspartic acid's side chain, ensuring its stability during synthesis. The "OPh" group indicates that the peptide is linked to a phenyl group, which may be used for further conjugation or immobilization purposes. This specific sequence and structure make "Z-Asp(OBut)-Gly-OPh" a valuable building block in the synthesis of larger peptides, proteins, or bioconjugates with potential applications in drug development, diagnostics, and materials science.
The CAS Registry Mumber 37784-09-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,7,7,8 and 4 respectively; the second part has 2 digits, 0 and 9 respectively. Calculate Digit Verification of CAS Registry Number 37784-09: (7*3)+(6*7)+(5*7)+(4*8)+(3*4)+(2*0)+(1*9)=151 151 % 10 = 1 So 37784-09-1 is a valid CAS Registry Number.
