5-Pyrimidinecarboxylic acid, 1,2,3,4-tetrahydro-4-phenyl-2-thioxo-6-(trifluoromethyl)-, ethyl ester is a complex organic compound with the chemical formula C16H14F3N2O2S. It is a derivative of pyrimidine, a heterocyclic aromatic organic compound consisting of a six-membered ring with four carbon atoms and two nitrogen atoms. This specific compound features a tetrahydro-4-phenyl-2-thioxo-6-(trifluoromethyl) structure, which means it has a saturated four-membered ring, a phenyl group attached to the fourth carbon, a sulfur atom replacing one of the oxygen atoms in the ring, and a trifluoromethyl group attached to the sixth carbon. The ethyl ester functional group is present, indicating that the carboxylic acid group is esterified with an ethyl group. 5-Pyrimidinecarboxylic acid, 1,2,3,4-tetrahydro-4-phenyl-2-thioxo-6-(trifluoromethyl)-, ethyl ester may have potential applications in pharmaceuticals or chemical research due to its unique structure and properties.

340-72-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 340-72-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,4 and 0 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 340-72:
(5*3)+(4*4)+(3*0)+(2*7)+(1*2)=47
47 % 10 = 7
So 340-72-7 is a valid CAS Registry Number.
