General Description
EGLIN C (41-49) is a peptide chemical compound that is a potent and specific inhibitor of human neutrophil elastase (HNE), an enzyme involved in inflammatory processes and tissue damage. This peptide is a synthetic analog of the natural elastase inhibitor elafin, with a modified cysteine residue that enhances its stability and efficacy. EGLIN C (41-49) has been shown to effectively inhibit HNE activity in vitro and in vivo, making it a potential candidate for the development of anti-inflammatory drugs and treatments for conditions such as chronic obstructive pulmonary disease (COPD), cystic fibrosis, and other inflammatory disorders. Its ability to specifically target and inhibit HNE without affecting other related enzymes makes it a promising compound for further research and development in the field of anti-inflammatory therapeutics.
Check Digit Verification of cas no
The CAS Registry Mumber 122299-11-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,2,9 and 9 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 122299-11:
(8*1)+(7*2)+(6*2)+(5*2)+(4*9)+(3*9)+(2*1)+(1*1)=110
110 % 10 = 0
So 122299-11-0 is a valid CAS Registry Number.
