"Z(OMe)-Gln-Glu(OBzl)-Arg(Mts)-Gly-Ala-OBzl" is a peptide sequence consisting of six amino acids: Z(OMe)-protected glutamine (Gln), benzyl-protected glutamic acid (Glu), 4-methyltrityl (Mts)-protected arginine (Arg), glycine (Gly), and alanine (Ala), with a benzyl-protected carboxylic acid group at the C-terminus. This specific arrangement of amino acids is designed to facilitate chemical synthesis and protect certain functional groups during the peptide assembly process. The protective groups, such as Z(OMe), OBzl, and Mts, are temporary modifications that prevent unwanted side reactions and are removed at specific stages of the synthesis to yield the desired peptide. This sequence represents a complex and carefully designed molecular structure with potential applications in pharmaceuticals, biotechnology, and materials science.
The CAS Registry Mumber 91682-71-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,6,8 and 2 respectively; the second part has 2 digits, 7 and 1 respectively. Calculate Digit Verification of CAS Registry Number 91682-71: (7*9)+(6*1)+(5*6)+(4*8)+(3*2)+(2*7)+(1*1)=152 152 % 10 = 2 So 91682-71-2 is a valid CAS Registry Number.
