Arsine, bis[2-(dimethylarsino)phenyl]methyl-, also known as 2,2'-dimethyl-2,2'-biphenylbis(dimethylarsine), is a chemical compound with the molecular formula C16H20As2. It is a derivative of arsine, an organoarsenic compound, and features a biphenyl core with two dimethylarsino groups attached to the 2-position of each phenyl ring. Arsine, bis[2-(dimethylarsino)phenyl]methyl- is of interest in the field of organometallic chemistry and may have potential applications in materials science and pharmaceuticals. However, due to its arsenic content, it is also considered toxic and requires careful handling.
The CAS Registry Mumber 2774-08-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,7 and 4 respectively; the second part has 2 digits, 0 and 8 respectively. Calculate Digit Verification of CAS Registry Number 2774-08: (6*2)+(5*7)+(4*7)+(3*4)+(2*0)+(1*8)=95 95 % 10 = 5 So 2774-08-5 is a valid CAS Registry Number.
