4-Trifluoromethyl-2-cyan-benzoic acid, also known as 4-(trifluoromethyl)-2-cyanobenzoic acid, is an organic compound with the chemical formula C9H4F3NO2. It is a derivative of benzoic acid, featuring a trifluoromethyl group (-CF3) at the 4-position and a cyano group (-CN) at the 2-position. 4-Trifluormethyl-2-cyan-benzoesaeure is characterized by its potential applications in the synthesis of pharmaceuticals, agrochemicals, and other specialty chemicals due to its unique electronic and steric properties. The presence of the trifluoromethyl group imparts lipophilicity and metabolic stability, while the cyano group can act as a Michael acceptor, making it a valuable building block in organic synthesis.

779-16-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 779-16-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,7 and 9 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 779-16:
(5*7)+(4*7)+(3*9)+(2*1)+(1*6)=98
98 % 10 = 8
So 779-16-8 is a valid CAS Registry Number.
