"Z(OMe)-Gly-Gln-Leu-Ser-NHNH2" is a peptide compound consisting of five amino acids: Z(OMe)-Gly (N-benzyloxycarbonyl-glycine), Gln (glutamine), Leu (leucine), and Ser (serine), with an NHNH2 group at the C-terminus. The Z(OMe) group is a protecting group used in peptide synthesis to prevent unwanted side reactions. This specific sequence of amino acids forms a linear peptide chain, which is a short protein-like molecule. Peptides like this one are often studied for their potential biological activities, such as acting as signaling molecules or having therapeutic applications. The sequence and the protecting group suggest that this peptide is likely used in research or pharmaceutical development, where the protecting group can be removed under specific conditions to reveal the free amino group, which is essential for further reactions or biological activity.
The CAS Registry Mumber 89762-62-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,7,6 and 2 respectively; the second part has 2 digits, 6 and 2 respectively. Calculate Digit Verification of CAS Registry Number 89762-62: (7*8)+(6*9)+(5*7)+(4*6)+(3*2)+(2*6)+(1*2)=189 189 % 10 = 9 So 89762-62-9 is a valid CAS Registry Number.
