O-propyl bis(aziridin-1-yl)phosphinothioate, also known as O-Propyl-Bis(Aziridinyl)Phosphinothioate or OBAP, is a chemical compound with the molecular formula C7H14N2O2PS. It is a derivative of phosphinothioic acid, featuring two aziridinyl groups attached to a phosphorus atom, which is further connected to an oxygen atom and a propyl group. OBAP is a colorless liquid with a pungent odor and is soluble in organic solvents. It is primarily used as a chemical warfare agent, specifically a nerve agent, due to its high toxicity and ability to inhibit the enzyme acetylcholinesterase, leading to the accumulation of acetylcholine in the nervous system and causing severe physiological effects. OBAP is considered a Schedule 1 chemical under the Chemical Weapons Convention, indicating its potential use in chemical warfare and the need for strict control over its production and use.

2590-44-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 2590-44-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,9 and 0 respectively; the second part has 2 digits, 4 and 4 respectively.Calculate Digit Verification of CAS Registry Number 2590-44:
(6*2)+(5*5)+(4*9)+(3*0)+(2*4)+(1*4)=85
85 % 10 = 5
So 2590-44-5 is a valid CAS Registry Number.
