"Z(OMe)-Glu(OBzl)-Val-NHNH-Troc" is a peptide sequence consisting of four amino acids: Z(OMe)-Glu, OBzl-Val, and NHNH-Troc. Z(OMe)-Glu refers to glutamic acid with a Z group (benzyloxycarbonyl) and a methoxy group, which are protecting groups used in peptide synthesis to prevent unwanted side reactions. OBzl-Val represents valine with a benzyl group, another protecting group. The sequence ends with NHNH-Troc, where NHNH is a terminal amine group and Troc stands for 2,2,2-trichloroethoxycarbonyl, a temporary protecting group for the amine. This specific sequence is designed for controlled peptide synthesis, where the protecting groups are strategically placed to facilitate the stepwise assembly of the peptide chain and prevent premature reactions. The use of these protecting groups is crucial for the successful synthesis of complex peptides and proteins in a laboratory setting.
The CAS Registry Mumber 83550-52-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,5,5 and 0 respectively; the second part has 2 digits, 5 and 2 respectively. Calculate Digit Verification of CAS Registry Number 83550-52: (7*8)+(6*3)+(5*5)+(4*5)+(3*0)+(2*5)+(1*2)=131 131 % 10 = 1 So 83550-52-1 is a valid CAS Registry Number.
