General Description
Benzene,1-nitro-4-[2-(phenylsulfonyl)ethyl]- is a chemical compound with the molecular formula C16H15NO5S. It consists of a benzene ring with a nitro group and an ethyl group attached at the 1 and 4 positions, respectively. Additionally, there is a phenylsulfonyl group attached to the ethyl group. Benzene,1-nitro-4-[2-(phenylsulfonyl)ethyl]- is often used in the pharmaceutical and chemical industries as a building block for the synthesis of various organic compounds. It has applications in the production of drugs, agrochemicals, and other fine chemicals. Additionally, it is important to handle this chemical with care as it is potentially hazardous and should be used in accordance with proper safety protocols.
Check Digit Verification of cas no
The CAS Registry Mumber 340041-90-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,0,0,4 and 1 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 340041-90:
(8*3)+(7*4)+(6*0)+(5*0)+(4*4)+(3*1)+(2*9)+(1*0)=89
89 % 10 = 9
So 340041-90-9 is a valid CAS Registry Number.
