"Z(OMe)-Cys(MBzl)-Ser-OMe" is a peptide-like molecule consisting of three amino acid residues: Z(OMe)-Cys, Ser, and OMe. Z(OMe)-Cys refers to a cysteine residue with a benzyl protecting group (MBzl) and an O-methyl group (OMe) on the side chain, which prevents unwanted side reactions and protects the thiol group during synthesis. Ser represents a serine residue, a polar amino acid with a hydroxyl group. The terminal OMe group is an O-methyl group attached to the carboxyl end of the peptide, which can influence the molecule's properties and reactivity. This specific sequence and modification are often used in peptide synthesis for various applications, such as drug development, chemical biology, and materials science, due to their unique chemical and biological properties.

Check Digit Verification of cas no

The CAS Registry Mumber 77693-99-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,6,9 and 3 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 77693-99:
(7*7)+(6*7)+(5*6)+(4*9)+(3*3)+(2*9)+(1*9)=193
193 % 10 = 3
So 77693-99-3 is a valid CAS Registry Number.

Fujii, Nobutaka,Yajima, Haruaki

, p. 811 - 818 (2007/10/02)

Commencing with the protected hexapentacontapeptide corresponding to the sequence Z(OMe)-(69-124)-OBzl of bovine pancreatic RNase A, chain elongation was carried out to the tetraoctacontapeptide, Z(OMe)-(RNase 41-124)-OBzl, by seven successive azide conde
