Benzenemethanesulfonic acid, ethyl ester, also known as ethyl benzyl sulfone or ethyl phenylmethyl sulfone, is an organic compound with the chemical formula C9H12O3S. It is a colorless liquid with a molecular weight of 208.26 g/mol. This ester is derived from benzenemethanesulfonic acid and ethanol, and it is characterized by the presence of a sulfone group (-SO2) attached to a benzene ring and an ethyl group (-CH2CH3) attached to the sulfone. Ethyl benzyl sulfone is used as an intermediate in the synthesis of various pharmaceuticals, agrochemicals, and other organic compounds. It is also employed as a solvent and a reagent in various chemical reactions. Due to its chemical properties, it is important to handle Benzenemethanesulfonic acid, ethyl ester with care, as it may cause irritation to the eyes, skin, and respiratory system.

Check Digit Verification of cas no

The CAS Registry Mumber 42454-54-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,4,5 and 4 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 42454-54:
(7*4)+(6*2)+(5*4)+(4*5)+(3*4)+(2*5)+(1*4)=106
106 % 10 = 6
So 42454-54-6 is a valid CAS Registry Number.
