Bis-(4-fluoro-phenyl)-arsinic acid, also known as 4,4'-difluorophenylarsinic acid, is an organoarsenic compound with the chemical formula C12H8AsF2O2. It is a white crystalline solid that is soluble in water and has a molecular weight of 321.04 g/mol. bis-(4-fluoro-phenyl)-arsinic acid is characterized by the presence of two 4-fluorophenyl groups attached to an arsonic acid backbone, which consists of an arsenic atom bonded to two hydroxyl groups and a carboxylic acid group. Bis-(4-fluoro-phenyl)-arsinic acid has potential applications in the fields of pharmaceuticals, agrochemicals, and materials science, particularly as a precursor for the synthesis of various organoarsenic compounds. Due to its arsenic content, it is considered toxic and requires proper handling and disposal to minimize environmental and health risks.

Check Digit Verification of cas no

The CAS Registry Mumber 3849-78-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,8,4 and 9 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 3849-78:
(6*3)+(5*8)+(4*4)+(3*9)+(2*7)+(1*8)=123
123 % 10 = 3
So 3849-78-3 is a valid CAS Registry Number.
