"Z-Pro-Arg(Mbs)-Gly-NH2" is a synthetic peptide consisting of five amino acids: Z (a protecting group), Proline (Pro), Arginine with a Methylbenzene Sulfonyl (Mbs) group attached (Arg(Mbs)), Glycine (Gly), and an Amide group (NH2) at the end. This sequence is often used in peptide synthesis and research due to its specific properties and reactivity. The Mbs group is a temporary protecting group for the guanidinium group of Arginine, which is crucial for preventing unwanted side reactions during peptide synthesis. Once the peptide is fully synthesized, the Mbs group can be removed to reveal the free guanidinium group, which is essential for the peptide's biological activity. This particular peptide sequence is of interest in various fields, including pharmaceuticals, where it may be used to study or mimic natural peptide functions, and in chemical research to understand peptide synthesis and protection strategies.
The CAS Registry Mumber 88333-78-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,8,3,3 and 3 respectively; the second part has 2 digits, 7 and 8 respectively. Calculate Digit Verification of CAS Registry Number 88333-78: (7*8)+(6*8)+(5*3)+(4*3)+(3*3)+(2*7)+(1*8)=162 162 % 10 = 2 So 88333-78-2 is a valid CAS Registry Number.
