"Z(OMe)-Ala-Arg(Mts)-Ala-Glu(OBzl)-Gln-Leu-NHNH-Troc" is a complex peptide sequence consisting of several amino acids and protecting groups. The sequence starts with Z(OMe)-Ala, where Z(OMe) is a protecting group for the amino group of alanine (Ala). This is followed by Arg(Mts), indicating that arginine (Arg) has an Mts protecting group on its side chain. The sequence continues with Ala, Glu(OBzl), where glutamic acid (Glu) has an OBzl (benzyl) protecting group on its side chain, and Gln, representing glutamine. The sequence ends with Leu, leucine, and NHNH-Troc, where NHNH is a terminal amine group and Troc is a protecting group for the amine. This peptide is likely used in chemical synthesis or as a building block for larger biomolecules, with the protecting groups ensuring that the peptide链 maintains its structure during synthesis and is only deprotected at the appropriate stages.
The CAS Registry Mumber 92265-11-7 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, 1 and 1 respectively. Calculate Digit Verification of CAS Registry Number 92265-11: (7*9)+(6*2)+(5*2)+(4*6)+(3*5)+(2*1)+(1*1)=127 127 % 10 = 7 So 92265-11-7 is a valid CAS Registry Number.
