28118-54-9

2-Methoxyimidazoline is a white powder chemical compound known for its multifunctional properties. It is particularly useful in the field of proteomics, where it serves as a lysine-specific label that enhances the overall sequence coverage obtained in peptide mapping experiments. This is achieved by increasing the ionization efficiencies of lysine-terminated tryptic fragments. Additionally, it acts as a labeling reagent for enhanced protein characterization with mass spectrometry and contains approximately 1% ethyleneurea.

Check Digit Verification of cas no

The CAS Registry Mumber 28118-54-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,1,1 and 8 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 28118-54:
(7*2)+(6*8)+(5*1)+(4*1)+(3*8)+(2*5)+(1*4)=109
109 % 10 = 9
So 28118-54-9 is a valid CAS Registry Number.
