Ethyl-difluoro-arsine, also known as ethyldifluoroarsine or C2H5AsF2, is a chemical compound consisting of an arsenic atom bonded to an ethyl group (C2H5) and two fluorine atoms. It is a colorless, volatile, and toxic liquid with a pungent odor. Ethyl-difluoro-arsine is a derivative of arsine (AsH3), where one hydrogen atom is replaced by an ethyl group and two hydrogen atoms are replaced by fluorine atoms. ethyl-difluoro-arsine is primarily used in the synthesis of various organoarsenic compounds and as a precursor in the production of certain semiconductor materials. Due to its toxicity and potential health risks, handling and storage of ethyl-difluoro-arsine require strict safety measures and precautions.

Check Digit Verification of cas no

The CAS Registry Mumber 430-40-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,3 and 0 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 430-40:
(5*4)+(4*3)+(3*0)+(2*4)+(1*0)=40
40 % 10 = 0
So 430-40-0 is a valid CAS Registry Number.
