"Z-Asp(OBut)-Lys(Boc)-OBut" is a peptide compound consisting of three amino acids: aspartic acid (Asp), lysine (Lys), and a terminal butyl group (OBut). The aspartic acid is N-terminally protected with a benzyloxycarbonyl (Z) group, while the lysine is protected with a tert-butyloxycarbonyl (Boc) group. The compound is a protected peptide, which means that the functional groups of the amino acids are temporarily blocked to prevent unwanted side reactions during synthesis. This specific sequence and protection scheme are often used in the synthesis of larger peptides or proteins, where controlled deprotection and coupling steps are necessary to build the desired sequence. The butyl groups (OBut) serve as protecting groups for the carboxylic acid groups of the aspartic acid and the terminal end of the peptide, ensuring that they remain unreactive until the desired time for coupling or deprotection.

Check Digit Verification of cas no

The CAS Registry Mumber 98229-40-4 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 9 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 98229-40:
(7*9)+(6*8)+(5*2)+(4*2)+(3*9)+(2*4)+(1*0)=164
164 % 10 = 4
So 98229-40-4 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
