Z-Asn-Ser(But)-Tyr(But)-OH is a synthetic peptide composed of four amino acids: Asparagine (Asn), Serine (Ser) with a tert-butyl (But) protecting group, Tyrosine (Tyr) with a tert-butyl (But) protecting group, and a terminal hydroxyl group (OH). This peptide is often used in chemical synthesis and research, particularly in the development of pharmaceuticals and other bioactive compounds. The tert-butyl protecting groups are used to prevent unwanted side reactions during peptide synthesis, ensuring that the peptide's structure remains intact until the desired point in the synthesis process. Once the peptide is fully assembled, the protecting groups can be removed to reveal the active peptide. This specific sequence of amino acids may have unique properties or functions, depending on the context in which it is used.

Check Digit Verification of cas no

The CAS Registry Mumber 98228-90-1 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 0 respectively.
Calculate Digit Verification of CAS Registry Number 98228-90:
(7*9)+(6*8)+(5*2)+(4*2)+(3*8)+(2*9)+(1*0)=171
171 % 10 = 1
So 98228-90-1 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
