"Z(OMe)-Thr-Glu-Asn-Tyr-NHNH2" is a peptide sequence consisting of six amino acids: Z(OMe), Thr (Threonine), Glu (Glutamic acid), Asn (Asparagine), Tyr (Tyrosine), and NHNH2 (a terminal group). The "Z(OMe)" refers to a protecting group, specifically a benzyloxycarbonyl (Z) group with a methoxyethyl (OMe) substitution, which is commonly used in peptide synthesis to protect the amino group of the first amino acid. This sequence is of interest in biochemistry and pharmaceuticals, as it may have specific biological activities or be a part of a larger protein structure. The peptide's properties, such as solubility, stability, and potential interactions with other molecules, are influenced by the specific arrangement and nature of these amino acids.
The CAS Registry Mumber 76063-58-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,0,6 and 3 respectively; the second part has 2 digits, 5 and 8 respectively. Calculate Digit Verification of CAS Registry Number 76063-58: (7*7)+(6*6)+(5*0)+(4*6)+(3*3)+(2*5)+(1*8)=136 136 % 10 = 6 So 76063-58-6 is a valid CAS Registry Number.
