General Description
Ethyl 5-chloro-1-(4-nitrophenyl)-1H-pyrazole-4-carboxylate is a chemical compound with the molecular formula C12H10ClN3O4. It is a pyrazole derivative that contains an ethyl ester group and a chloride and nitrophenyl substituent on the pyrazole ring. Ethyl 5-chloro-1-(4-nitrophenyl)-1H-pyrazole-4-carboxylate has been used in pharmaceutical research as a potential building block for the synthesis of new drugs with biological activity. The presence of the nitrophenyl group suggests that this compound may have potential as an anti-inflammatory or analgesic agent, as nitrophenyl derivatives have been investigated for these properties in the past. Additionally, the chlorine substituent may also have implications for the compound's activity and potential uses.
Check Digit Verification of cas no
The CAS Registry Mumber 110821-37-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,0,8,2 and 1 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 110821-37:
(8*1)+(7*1)+(6*0)+(5*8)+(4*2)+(3*1)+(2*3)+(1*7)=79
79 % 10 = 9
So 110821-37-9 is a valid CAS Registry Number.
