Check Digit Verification of cas no

The CAS Registry Mumber 98534-25-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,5,3 and 4 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 98534-25:
(7*9)+(6*8)+(5*5)+(4*3)+(3*4)+(2*2)+(1*5)=169
169 % 10 = 9
So 98534-25-9 is a valid CAS Registry Number.

Synthesis of 1-Aryl-5-(trifluoromethyl)-1H-pyrazole-4-carboxylic Acids and Esters

Beck, James R.,Wright, Fred L.

, p. 739 - 740 (2007/10/02)

Ethyl 1-aryl-5-(trifluoromethyl)-1H-pyrazole-4-carboxylates 2 were prepared by the condensation of arylhydrazines with ethyl 3-ethoxy-2-(trifluoroacetyl)-2-propenoate (1a) at low temperature.The corresponding acids were also synthesized.X-ray diffraction analysis of an amide derivative 4 verified the position of the trifluoromethyl group on the pyrazole ring.
