Butyl-chloro-phenyl-arsine, also known as bis(4-chlorophenyl)methylarsine or C12H12AsCl, is an organoarsenic compound characterized by the presence of a butyl group, a chloro group, and a phenyl group attached to an arsenic atom. This chemical is primarily used as a precursor in the synthesis of various organoarsenic compounds, which have applications in the fields of pharmaceuticals, agrochemicals, and materials science. Due to its potential toxicity and environmental impact, handling and disposal of butyl-chloro-phenyl-arsine must be carried out with proper safety measures and in accordance with relevant regulations.
The CAS Registry Mumber 3399-95-9 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, 9 and 5 respectively. Calculate Digit Verification of CAS Registry Number 3399-95: (6*3)+(5*3)+(4*9)+(3*9)+(2*9)+(1*5)=119 119 % 10 = 9 So 3399-95-9 is a valid CAS Registry Number.
