3,17β-Bis[(3-pyridinylcarbonyl)oxy]-estra-1,3,5(10)-triene is a complex organic compound with the molecular formula C28H20N2O6. It is a derivative of estratriene, a naturally occurring estrogen hormone, with two pyridinylcarbonyloxy groups attached to the 3 and 17β positions. This modification enhances the compound's affinity for estrogen receptors, making it a potent selective estrogen receptor modulator (SERM). The compound is used in research to study the effects of estrogen on various biological processes, such as bone density, cholesterol levels, and reproductive system function. Due to its specific binding properties, it can exhibit both agonistic and antagonistic effects on estrogen receptors, depending on the target tissue.
The CAS Registry Mumber 4248-62-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,4 and 8 respectively; the second part has 2 digits, 6 and 2 respectively. Calculate Digit Verification of CAS Registry Number 4248-62: (6*4)+(5*2)+(4*4)+(3*8)+(2*6)+(1*2)=88 88 % 10 = 8 So 4248-62-8 is a valid CAS Registry Number.
