"Z-Trp-Asn-Ser(But)-Tyr(But)-OH" is a peptide compound consisting of five amino acids: Z-Trp (N-benzyloxycarbonyl-tryptophan), Asn (asparagine), Ser(But) (N-t-butoxycarbonyl-serine), Tyr(But) (N-t-butoxycarbonyl-tyrosine), and OH (hydroxyl group). This sequence is protected with benzyl and t-butyl groups, which are commonly used in peptide synthesis to prevent unwanted side reactions and ensure the correct formation of peptide bonds. The presence of these protecting groups indicates that Z-Trp-Asn-Ser(But)-Tyr(But)-OH is likely an intermediate in the synthesis of a larger peptide or protein. The hydroxyl group at the end suggests that this peptide is not yet fully elongated and may be part of a longer chain that is still under construction. Z-Trp-Asn-Ser(But)-Tyr(But)-OH is significant in the field of biochemistry and pharmaceuticals, as it represents a building block for the creation of more complex biologically active molecules.

Check Digit Verification of cas no

The CAS Registry Mumber 98228-92-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,2,2 and 8 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 98228-92:
(7*9)+(6*8)+(5*2)+(4*2)+(3*8)+(2*9)+(1*2)=173
173 % 10 = 3
So 98228-92-3 is a valid CAS Registry Number.

Synthesis of the Hypothetical Active Site of the Nerve Growth Factor

Wuensch, Erich

, p. 505 - 524 (2007/10/02)

The synthesis of an unsymmetrical cystine peptide corresponding to the sequence 10-25/75-88 of mouse nerve growth factor was performed via the newly developed sulfenohydrazide procedure.The triacontapeptide isolated at a high degree of purity after Sephadex-LH 20 chromatography, did not exhibit in the biological assays the expected nerve growth factor activity as reported by Revoltella and coworkers. - Keywords: Nerve growth factor; Peptide synthesis; Unsymmetrical cystine peptides
