4-Nitro-2-trifluoromethyl-benzenesulfonic acid is a chemical compound characterized by its molecular formula C7H4F3NO5S. It features a benzene ring with a nitro group at the 4-position, a trifluoromethyl group at the 2-position, and a sulfonic acid group attached to the benzene ring. 4-nitro-2-trifluoromethyl-benzenesulfonic acid is known for its acidic properties due to the presence of the sulfonic acid group, which can ionize in water to release hydrogen ions. The trifluoromethyl group contributes to the compound's lipophilicity, while the nitro group imparts a strong electron-withdrawing effect, influencing the compound's reactivity and stability. It is a white to off-white crystalline solid and is typically used in the synthesis of pharmaceuticals and other organic compounds due to its unique reactivity profile.

Check Digit Verification of cas no

The CAS Registry Mumber 2968-47-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,6 and 8 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 2968-47:
(6*2)+(5*9)+(4*6)+(3*8)+(2*4)+(1*7)=120
120 % 10 = 0
So 2968-47-0 is a valid CAS Registry Number.
