Arsenoacetic acid, also known as cacodylic acid, is an organoarsenic compound with the chemical formula (CH3)2AsO2H. It is a colorless, oily liquid with a strong, unpleasant odor. Arsenoacetic acid was historically used as a herbicide and insecticide, but its use has been discontinued due to its high toxicity and potential carcinogenic properties. It can cause severe health issues, including skin irritation, respiratory problems, and damage to the nervous system. Due to its hazardous nature, arsenoacetic acid is now considered a hazardous waste and is strictly regulated in many countries.

Check Digit Verification of cas no

The CAS Registry Mumber 544-27-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,4 and 4 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 544-27:
(5*5)+(4*4)+(3*4)+(2*2)+(1*7)=64
64 % 10 = 4
So 544-27-4 is a valid CAS Registry Number.
