N-octyl methylphosphonic acid (NOMPA) is an organophosphorus compound with the chemical formula C9H21O2P. It is a colorless, oily liquid that is soluble in water and organic solvents. NOMPA is a degradation product of certain chemical warfare agents, such as the nerve agent VX, and is often used as a marker to detect the presence of these agents. It is not volatile and has a relatively low toxicity compared to its parent compounds, but it can still pose health risks if ingested or inhaled in large quantities. Due to its association with chemical weapons, NOMPA is a subject of interest in the fields of chemical defense and environmental monitoring.

1832-58-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1832-58-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,3 and 2 respectively; the second part has 2 digits, 5 and 8 respectively.Calculate Digit Verification of CAS Registry Number 1832-58:
(6*1)+(5*8)+(4*3)+(3*2)+(2*5)+(1*8)=82
82 % 10 = 2
So 1832-58-2 is a valid CAS Registry Number.
