Dibutylchloroarsine, also known as DBAC, is an organoarsenic compound with the chemical formula C8H18AsCl. It is a colorless, oily liquid with a pungent odor and is primarily used as a chemical warfare agent. DBAC was first synthesized in 1924 and was later developed as a potential chemical weapon during World War II. It is highly toxic and can cause severe health issues, including respiratory distress, vomiting, and death. Due to its potential for misuse, the production and stockpiling of dibutylchloroarsine are now regulated under international treaties.
The CAS Registry Mumber 3399-89-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,3,9 and 9 respectively; the second part has 2 digits, 8 and 9 respectively. Calculate Digit Verification of CAS Registry Number 3399-89: (6*3)+(5*3)+(4*9)+(3*9)+(2*8)+(1*9)=121 121 % 10 = 1 So 3399-89-1 is a valid CAS Registry Number.
