(E)-1-Phenylmethanesulfonyl-cyclopentadecene is a complex organic chemical compound with the molecular formula C22H28O2S. It features a cyclopentadecene ring, which is a 15-carbon cyclic alkene, with a phenylmethanesulfonyl group attached to the 1-position. The phenylmethanesulfonyl group consists of a benzene ring attached to a methanesulfonyl moiety, which is a methane molecule with a sulfonyl group (-SO2-) replacing one of the hydrogen atoms. (E)-1-Phenylmethanesulfonyl-cyclopentadecene is characterized by the (E)-configuration, indicating the geometric arrangement of the double bond in the molecule. It is an important intermediate in the synthesis of various pharmaceuticals and agrochemicals due to its unique structure and reactivity.

Check Digit Verification of cas no

The CAS Registry Mumber 84201-31-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,2,0 and 1 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 84201-31:
(7*8)+(6*4)+(5*2)+(4*0)+(3*1)+(2*3)+(1*1)=100
100 % 10 = 0
So 84201-31-0 is a valid CAS Registry Number.
