General Description
1-[[(4-Nitrophenyl)methyl]sulfonyl]-pyrrolidine is a chemical compound that is structurally classified as a sulfone and an aromatic compound, specifically a nitrocompound. The nitrocompound part of this molecule includes a nitrophenyl group attached to a methylene bridge. This is followed by a sulfone group, which is a sulfur atom doubly bonded with two oxygen atoms, and singly bonded with two carbon atoms to form a cyclic structure. Lastly, the presence of a pyrrolidine, a five-membered ring with a nitrogen atom and four carbon atoms, finishes the structure. Detailed information about its physical properties, toxicity, and specific applications is less widely available, indicating that it may not be extensively used or studied.
Check Digit Verification of cas no
The CAS Registry Mumber 340041-91-0 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 1 respectively.
Calculate Digit Verification of CAS Registry Number 340041-91:
(8*3)+(7*4)+(6*0)+(5*0)+(4*4)+(3*1)+(2*9)+(1*1)=90
90 % 10 = 0
So 340041-91-0 is a valid CAS Registry Number.
