N2-ethyl-3-chloro-5-trifluoromethanesulfonyl-o-phenylenediamine is a complex organic compound with the molecular formula C9H10ClF3N2O2S. It is characterized by the presence of an ethyl group (-C2H5) attached to the nitrogen atom, a chlorine atom (-Cl) at the 3-position, and a trifluoromethanesulfonyl group (-CF3SO2) at the 5-position of the o-phenylenediamine backbone. N2-ethyl-3-chloro-5-trifluoromethanesulfonyl-o-phenylenediamine is known for its reactivity and is often used in chemical synthesis, particularly in the preparation of dyes and pharmaceuticals. Its structure provides it with unique properties, such as increased stability and reactivity due to the electron-withdrawing nature of the trifluoromethanesulfonyl group.

Check Digit Verification of cas no

The CAS Registry Mumber 1549-54-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,4 and 9 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1549-54:
(6*1)+(5*5)+(4*4)+(3*9)+(2*5)+(1*4)=88
88 % 10 = 8
So 1549-54-8 is a valid CAS Registry Number.
