Z-Cys(-CH2-Ph)-Gly-ONB is a synthetic peptide compound consisting of three amino acids: Z-Cys(-CH2-Ph), Gly, and ONB. The Z-Cys(-CH2-Ph) represents a cysteine residue with a phenylmethyl group (Ph-CH2-) attached to it, which is a common modification used in peptide synthesis to protect the thiol group of cysteine. Gly is glycine, the simplest amino acid, and ONB stands for ortho-nitrobenzyl, which is a protecting group used for the amino group of the peptide. Z-Cys(-CH2-Ph)-Gly-ONB is often used in peptide synthesis as a building block, particularly in the construction of larger peptides or proteins where specific chemical modifications are required. The presence of the Z group and ONB allows for controlled synthesis and selective deprotection steps, which are crucial in the assembly of complex peptide structures.

51782-11-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 51782-11-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,7,8 and 2 respectively; the second part has 2 digits, 1 and 1 respectively.Calculate Digit Verification of CAS Registry Number 51782-11:
(7*5)+(6*1)+(5*7)+(4*8)+(3*2)+(2*1)+(1*1)=117
117 % 10 = 7
So 51782-11-7 is a valid CAS Registry Number.
