1-(3-Chloro-phenyl)-3-methyl-1H-pyrazolo[3,4-b]pyrazine-5,6-dicarboxylic acid diethyl ester is a complex organic compound with the molecular formula C18H17ClN2O4. It is characterized by a pyrazolo[3,4-b]pyrazine core, which is a fused ring system consisting of a pyrazine and a pyrazole. The molecule features a 3-chlorophenyl group attached to the pyrazolo[3,4-b]pyrazine ring, contributing to its chemical properties. Additionally, it has a methyl group at the 3-position and two diethyl ester groups attached to the 5 and 6 positions of the dicarboxylic acid, which can influence its reactivity and solubility. 1-(3-Chloro-phenyl)-3-methyl-1H-pyrazolo[3,4-b]pyrazine-5,6-dicarboxylic acid diethyl ester may be of interest in medicinal chemistry or as a synthetic intermediate due to its unique structure and potential for further functionalization.
The CAS Registry Mumber 90094-67-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,0,9 and 4 respectively; the second part has 2 digits, 6 and 7 respectively. Calculate Digit Verification of CAS Registry Number 90094-67: (7*9)+(6*0)+(5*0)+(4*9)+(3*4)+(2*6)+(1*7)=130 130 % 10 = 0 So 90094-67-0 is a valid CAS Registry Number.
