Ethyl N-carbethoxyvalerimidate, also known as ECVI, is a chemical compound with the molecular formula C11H19NO3. It is a reagent used in organic synthesis, particularly for the preparation of peptides and other biologically active molecules. ECVI is a protected amino acid derivative, where the amino group is protected by a carbethoxy group, allowing for selective reactions at the carboxyl group without affecting the amino group. This selective reactivity is crucial in the synthesis of complex molecules, as it enables chemists to build peptide chains in a controlled manner. ECVI is also known for its stability and ease of use, making it a valuable tool in the field of peptide chemistry and drug development.

5133-68-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5133-68-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,3 and 3 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 5133-68:
(6*5)+(5*1)+(4*3)+(3*3)+(2*6)+(1*8)=76
76 % 10 = 6
So 5133-68-6 is a valid CAS Registry Number.
