71989-29-2 Usage
General Description
FMOC-MET-ONP is a chemical compound consisting of three main components: FMOC, MET, and ONP. FMOC, or 9-fluorenylmethoxycarbonyl, is a protecting group used in peptide synthesis to protect the amine group of amino acids. MET, or methionine, is an essential amino acid found in proteins and involved in various biological functions. ONP, or o-nitrophenol, is a common chromogenic substrate used in enzymatic assays, particularly for the detection of phosphatases. When combined, FMOC-MET-ONP can be used as a useful tool in peptide chemistry and enzymatic assays, making it an important chemical in biochemistry and biomedical research.
Check Digit Verification of cas no
The CAS Registry Mumber 71989-29-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,9,8 and 9 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 71989-29:
(7*7)+(6*1)+(5*9)+(4*8)+(3*9)+(2*2)+(1*9)=172
172 % 10 = 2
So 71989-29-2 is a valid CAS Registry Number.
