Ethyl methyl phosphorofluoridate, also known as EMPF or sarin, is a highly toxic organophosphorus compound that acts as a potent nerve agent. It was first synthesized in 1938 by German scientists and later weaponized during World War II. Sarin is a colorless, odorless, and tasteless liquid that can be easily dispersed through the air, making it a dangerous chemical warfare agent. It inhibits the enzyme acetylcholinesterase, leading to the accumulation of acetylcholine in the nervous system and causing severe symptoms such as convulsions, respiratory failure, and death. Due to its extreme toxicity, sarin is classified as a Schedule 1 chemical weapon under the Chemical Weapons Convention, and its production and use are strictly regulated.

Check Digit Verification of cas no

The CAS Registry Mumber 430-05-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,3 and 0 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 430-05:
(5*4)+(4*3)+(3*0)+(2*0)+(1*5)=37
37 % 10 = 7
So 430-05-7 is a valid CAS Registry Number.
