"Z-Arg(NO2)-Lys(Z)-Asp(OBzl)-Val-Tyr-OMe" is a peptide sequence consisting of six amino acids: Z-protected arginine with a nitro group (Arg(NO2)), Z-protected lysine (Lys(Z)), benzyl-protected aspartic acid (Asp(OBzl)), valine (Val), and tyrosine with a methoxy group (Tyr-OMe). This specific arrangement of amino acids is designed to study or mimic certain biological functions, with the protective groups (Z and OBzl) preventing unwanted side reactions during synthesis or in biological environments. The nitro group on the arginine and the methoxy group on the tyrosine are likely included for specific chemical or biological properties. This peptide sequence could be used in various applications, such as drug development, understanding protein-protein interactions, or as a component in biochemical research.
The CAS Registry Mumber 75957-70-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,9,5 and 7 respectively; the second part has 2 digits, 7 and 0 respectively. Calculate Digit Verification of CAS Registry Number 75957-70: (7*7)+(6*5)+(5*9)+(4*5)+(3*7)+(2*7)+(1*0)=179 179 % 10 = 9 So 75957-70-9 is a valid CAS Registry Number.
