17β-acetoxy-3-hydroxy-1,3,5(10)-estratriene-6-onoxime is a complex organic compound belonging to the class of steroids, specifically a derivative of estradiol, a naturally occurring estrogen hormone. This chemical features a 17β-acetoxy group, which is an acetate ester at the 17β position, a 3-hydroxy group, and a 6-onoxime group, which is a derivative of a nitrile oxide. The compound's structure is characterized by a 1,3,5(10)-estratriene backbone, which is a tricyclic arrangement of carbon atoms with double bonds at the 1, 3, and 10 positions. The presence of the onoxime group at the 6 position distinguishes it from other estradiol derivatives. This chemical is of interest in the field of pharmaceuticals and endocrinology due to its potential applications in hormone therapy and research into the effects of estrogen on the body.
The CAS Registry Mumber 6563-80-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,5,6 and 3 respectively; the second part has 2 digits, 8 and 0 respectively. Calculate Digit Verification of CAS Registry Number 6563-80: (6*6)+(5*5)+(4*6)+(3*3)+(2*8)+(1*0)=110 110 % 10 = 0 So 6563-80-0 is a valid CAS Registry Number.
