The chemical sequence "Z(OMe)-Gln-Ser-Ser-Glu(OBzl)-Gly-Phe-Pro-Ser-Glu(OBzl)-Met(O)-OBzl" represents a peptide, which is a chain of amino acids. In this specific peptide, the amino acids are linked together in the following order: Z(OMe)-protected glutamine (Gln), serine (Ser), another serine (Ser), benzyl-protected glutamic acid (Glu(OBzl)), glycine (Gly), phenylalanine (Phe), proline (Pro), serine (Ser), another benzyl-protected glutamic acid (Glu(OBzl)), and methionine with an oxygen atom attached (Met(O)). The terminal benzyl group (OBzl) indicates that the peptide is capped with a benzyl protecting group. This sequence is likely part of a larger bioactive molecule or a component in a chemical synthesis process, where the protecting groups are used to prevent unwanted side reactions during synthesis and are removed at a later stage to reveal the active peptide.
The CAS Registry Mumber 84866-58-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,8,6 and 6 respectively; the second part has 2 digits, 5 and 8 respectively. Calculate Digit Verification of CAS Registry Number 84866-58: (7*8)+(6*4)+(5*8)+(4*6)+(3*6)+(2*5)+(1*8)=180 180 % 10 = 0 So 84866-58-0 is a valid CAS Registry Number.
