"Z(OMe)-Thr-Asn-Ser-Tyr-OMe" is a peptide sequence consisting of five amino acids: Z(OMe), Thr, Asn, Ser, and Tyr, with OMe groups at both the N- and C-termini. Z(OMe) represents a protected form of the amino acid, where the α-amino group is blocked by a benzyloxycarbonyl (Cbz) group, and the OMe group is a methoxyethyl group. Thr (threonine), Asn (asparagine), Ser (serine), and Tyr (tyrosine) are naturally occurring amino acids that play crucial roles in protein structure and function. This specific sequence may have potential applications in pharmaceuticals, drug development, or as a building block for larger peptide or protein structures.
The CAS Registry Mumber 90709-84-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,7,0 and 9 respectively; the second part has 2 digits, 8 and 4 respectively. Calculate Digit Verification of CAS Registry Number 90709-84: (7*9)+(6*0)+(5*7)+(4*0)+(3*9)+(2*8)+(1*4)=145 145 % 10 = 5 So 90709-84-5 is a valid CAS Registry Number.
