C-reactive protein (CRP) is a sensitive acute-phase protein produced by the liver in response to inflammation or infection. It is a crucial biomarker used in clinical settings to monitor inflammation levels and assess the risk of various diseases, such as cardiovascular events, autoimmune disorders, and infections. CRP binds to phosphocholine on the surface of dying cells and pathogens, activating the complement system and enhancing phagocytosis by immune cells. High-sensitivity CRP (hs-CRP) tests are particularly useful for detecting low levels of CRP, which can indicate a higher risk of cardiovascular disease. In summary, C-reactive protein is a vital inflammatory marker that plays a significant role in the immune response and serves as an important diagnostic tool in medicine.
The CAS Registry Mumber 9009-76-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,0 and 9 respectively; the second part has 2 digits, 7 and 6 respectively. Calculate Digit Verification of CAS Registry Number 9009-76: (6*9)+(5*0)+(4*0)+(3*9)+(2*7)+(1*6)=101 101 % 10 = 1 So 9009-76-1 is a valid CAS Registry Number.
