3,3-dimethyl-2-butyl methylphosphonofluoridate, also known as QL, is a potent organophosphorus compound that belongs to the class of G-series nerve agents. It is a colorless, odorless, and tasteless liquid, making it difficult to detect in the environment. QL is a highly toxic substance that inhibits the enzyme acetylcholinesterase, leading to the accumulation of acetylcholine in the nervous system and causing severe physiological effects, including muscle twitching, seizures, and respiratory failure. Due to its high toxicity, rapid onset, and potential for large-scale casualties, QL is considered a significant threat in both military and terrorist scenarios. It is important to note that the correct chemical name for 3,3-dimethyl-2-butyl methylphosphonofluoridate is "3,3-dimethyl-2-butan-2-yl methylphosphonofluoridate," and it is often referred to by its NATO designation "GF" or "QL."

660-21-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 660-21-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,6 and 0 respectively; the second part has 2 digits, 2 and 1 respectively.Calculate Digit Verification of CAS Registry Number 660-21:
(5*6)+(4*6)+(3*0)+(2*2)+(1*1)=59
59 % 10 = 9
So 660-21-9 is a valid CAS Registry Number.
