Nα-Formyl-Nε-benzyloxycarbonyl-lys, also known as Z-Formyl-Lys, is a chemical compound derived from the amino acid lysine. It is a protected form of lysine, where the amino group (Nα) is formylated and the ε-amino group is protected by a benzyloxycarbonyl (Z) group. Nα-Formyl-Nε-benzyloxycarbonyl-lys is commonly used in peptide synthesis as a building block, particularly in solid-phase peptide synthesis (SPPS). The Z group serves to protect the ε-amino group from unwanted side reactions during the synthesis process, while the formyl group at the Nα position can be used for specific chemical modifications or as a handle for further reactions. The use of Z-Formyl-Lys allows for the controlled assembly of peptides with precise sequences and functionalities, which is crucial in the development of pharmaceuticals, bioactive peptides, and other biotechnological applications.

Check Digit Verification of cas no

The CAS Registry Mumber 6416-98-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,1 and 6 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 6416-98:
(6*6)+(5*4)+(4*1)+(3*6)+(2*9)+(1*8)=104
104 % 10 = 4
So 6416-98-4 is a valid CAS Registry Number.
