DL-3-methoxy-D-homoestra-1,3,5(10),8,14-pentaen-17a-one is a complex organic compound with the molecular formula C21H32O2. It is a derivative of the steroidal structure, specifically a D-homoestrogen, which is a type of hormone that is structurally similar to estrogen but with a different carbon skeleton. The compound is characterized by the presence of a 3-methoxy group, which is a methoxy (-OCH3) functional group attached to the third carbon atom, and a 17a-ketone group, indicating a ketone (C=O) at the 17th carbon position with the alpha (a) configuration. DL-3-methoxy-D-homoestra-1,3,5(10),8,14-pentaen-17a-one is of interest in the field of chemistry and pharmacology, particularly in the study of hormone-like substances and their potential applications in medicine.
The CAS Registry Mumber 1456-49-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,5 and 6 respectively; the second part has 2 digits, 4 and 9 respectively. Calculate Digit Verification of CAS Registry Number 1456-49: (6*1)+(5*4)+(4*5)+(3*6)+(2*4)+(1*9)=81 81 % 10 = 1 So 1456-49-1 is a valid CAS Registry Number.
