The chemical sequence "Z(OMe)-Ser-Arg(Mts)-Gln-Gln-Gly-Glu(OBzl)-Ser-Asn-Gln-Glu(OBzl)-NH2" represents a peptide with a specific structure. This peptide is composed of a series of amino acids, each denoted by its three-letter code, and is modified with various chemical groups. The "Z(OMe)" at the beginning indicates that the peptide is protected with a benzyloxycarbonyl (Z) group, which is a common protecting group in peptide synthesis, and the "OMe" suggests the presence of a methoxy group. The "Arg(Mts)" denotes an arginine residue with a 4-methyltrityl (Mts) group, which is used for purification and detection purposes. "Gln" stands for glutamine, "Gly" for glycine, "Glu(OBzl)" for glutamic acid with a benzyl (OBzl) protecting group, "Ser" for serine, "Asn" for asparagine, and "NH2" indicates the free amine group at the C-terminus of the peptide. This sequence is likely part of a larger biologically active molecule or a synthetic compound designed for specific research or therapeutic purposes.
The CAS Registry Mumber 92086-15-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,0,8 and 6 respectively; the second part has 2 digits, 1 and 5 respectively. Calculate Digit Verification of CAS Registry Number 92086-15: (7*9)+(6*2)+(5*0)+(4*8)+(3*6)+(2*1)+(1*5)=132 132 % 10 = 2 So 92086-15-2 is a valid CAS Registry Number.
