"Z(OMe)-Met(O)-Glu(OBzl)-Ile-Ile-NH2" is a peptide sequence consisting of five amino acids: Z(OMe)-Met(O), Glu(OBzl), Ile, Ile, and NH2. Z(OMe)-Met(O) refers to a methoxylated and oxidized methionine, while Glu(OBzl) denotes a glutamic acid with a benzyl ester protecting group. The two Ile residues represent isoleucine amino acids. The NH2 at the end signifies the presence of a primary amine group, indicating that this peptide is a C-terminal amidated peptide. This sequence is characterized by its specific arrangement of amino acids and protective groups, which play a crucial role in its stability, reactivity, and potential biological activity.
The CAS Registry Mumber 92265-08-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,2,6 and 5 respectively; the second part has 2 digits, 0 and 8 respectively. Calculate Digit Verification of CAS Registry Number 92265-08: (7*9)+(6*2)+(5*2)+(4*6)+(3*5)+(2*0)+(1*8)=132 132 % 10 = 2 So 92265-08-2 is a valid CAS Registry Number.
