"Z(OMe)-Ala-Gln-Ser-Gly-NHNH2" is a peptide compound consisting of five amino acids: Z(OMe)-alanine, glutamine, serine, glycine, and a terminal amino group (NHNH2). The "Z(OMe)" group is a protecting group for the alanine residue, which is used in peptide synthesis to prevent unwanted side reactions. This specific sequence of amino acids forms a short peptide chain, which is a building block of proteins. Peptides like this one are often studied for their potential biological activities, such as acting as signaling molecules or having therapeutic applications. The terminal amino group (NHNH2) is characteristic of peptides that are not further extended or cyclized, indicating that this is a linear peptide.
The CAS Registry Mumber 99236-54-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,2,3 and 6 respectively; the second part has 2 digits, 5 and 4 respectively. Calculate Digit Verification of CAS Registry Number 99236-54: (7*9)+(6*9)+(5*2)+(4*3)+(3*6)+(2*5)+(1*4)=171 171 % 10 = 1 So 99236-54-1 is a valid CAS Registry Number.
