Dimethylcyanoarsine, also known as (CH3)2AsCN, is a highly toxic chemical compound that belongs to the class of organoarsenic compounds. It is a colorless, volatile liquid with a pungent odor and is soluble in water. Dimethylcyanoarsine was historically used as a chemical warfare agent, particularly during World War II, due to its ability to inhibit the activity of acetylcholinesterase, an enzyme crucial for the proper functioning of the nervous system. Exposure to dimethylcyanoarsine can lead to severe health effects, including respiratory distress, seizures, and even death. It is important to note that the use of such chemicals in warfare is prohibited under international law, and their production and stockpiling are strictly regulated.

683-45-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 683-45-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,8 and 3 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 683-45:
(5*6)+(4*8)+(3*3)+(2*4)+(1*5)=84
84 % 10 = 4
So 683-45-4 is a valid CAS Registry Number.
