"Z(OMe)-Gly-Trp(Mts)-Thr-NHNH2" is a peptide compound consisting of four amino acids: Z(OMe)-Gly, Trp(Mts), Thr, and NHNH2. Z(OMe)-Gly refers to glycine with a benzyloxycarbonyl (Z) protecting group and a methoxy group (OMe), which is crucial for protecting the amino group during peptide synthesis. Trp(Mts) denotes tryptophan with a 4-methyltrityl (Mts) group, which serves as a photolabile protecting group for the side chain. Thr represents threonine, an amino acid with a hydroxyl group on its side chain. The peptide is capped with NHNH2, indicating a free amino group at the C-terminus. This sequence is likely used in peptide synthesis research, where the protecting groups are removed to allow for further reactions or to study the peptide's properties.
The CAS Registry Mumber 98477-84-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,4,7 and 7 respectively; the second part has 2 digits, 8 and 4 respectively. Calculate Digit Verification of CAS Registry Number 98477-84: (7*9)+(6*8)+(5*4)+(4*7)+(3*7)+(2*8)+(1*4)=200 200 % 10 = 0 So 98477-84-0 is a valid CAS Registry Number.
