"N-(O-acetyl-N-benzyloxycarbonyl-L-tyrosyl)-L-tyrosine ethyl ester" is a complex organic compound with the molecular formula C31H33NO8. It is a derivative of L-tyrosine, an amino acid, and is characterized by the presence of an ethyl ester group, an acetyl group, and a benzyloxycarbonyl (Z) protecting group. N-(O-acetyl-N-benzyloxycarbonyl-L-tyrosyl)-L-tyrosine ethyl ester is often used in peptide synthesis as a building block, where the protecting groups are crucial for preventing unwanted side reactions during the assembly of peptide chains. The acetyl group protects the hydroxyl group, while the benzyloxycarbonyl group protects the amino group, allowing for controlled peptide bond formation. Once the peptide is fully synthesized, these protecting groups can be removed to reveal the final peptide sequence.

Check Digit Verification of cas no

The CAS Registry Mumber 6425-74-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,2 and 5 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 6425-74:
(6*6)+(5*4)+(4*2)+(3*5)+(2*7)+(1*4)=97
97 % 10 = 7
So 6425-74-7 is a valid CAS Registry Number.
