"Z-Gln-Asn-Cys(Trt)-Pro-Arg(Mbs)-OtBu" is a peptide sequence consisting of six amino acids: glutamine (Gln), asparagine (Asn), cysteine (Cys) with a trityl (Trt) protecting group, proline (Pro), and arginine (Arg) with a 4-methoxybenzenesulfonyl (Mbs) protecting group, and a tert-butyl (tBu) group at the C-terminus. This specific arrangement of amino acids is designed to protect certain functional groups during peptide synthesis, which is crucial for the formation of the desired peptide bonds and the overall structure of the peptide. The protecting groups (Trt and Mbs) are temporary modifications that shield the side chains of cysteine and arginine, respectively, from unwanted reactions until they are removed at a later stage in the synthesis process. The OtBu group serves to protect the C-terminus, ensuring that the peptide chain does not extend further than intended. This sequence is a common intermediate in the synthesis of larger, more complex peptides and proteins, and the use of protecting groups is a key strategy in modern peptide chemistry to control the reaction specificity and yield of the desired product.

90303-76-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 90303-76-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,3,0 and 3 respectively; the second part has 2 digits, 7 and 6 respectively.Calculate Digit Verification of CAS Registry Number 90303-76:
(7*9)+(6*0)+(5*3)+(4*0)+(3*3)+(2*7)+(1*6)=107
107 % 10 = 7
So 90303-76-7 is a valid CAS Registry Number.
