3-Methoxy-8,14-seco-19-nor-homoandrosta-2,5(10),9(11)-trien-14,17a-dion is a complex organic compound with a molecular formula of C21H26O3. It is a derivative of the steroidal structure, specifically a modified version of the androstane family. 3-Methoxy-8,14-seco-19-nor-homoandrosta-2,5(10),9(11)-trien-14,17a-dion features a 3-methoxy group, which is a methoxy (-OCH3) functional group attached to the third carbon atom. The "8,14-seco" part of the name indicates that there is a break in the carbon skeleton at the 8 and 14 positions, which is characteristic of a seco-steroid. The "19-nor" prefix signifies that one carbon atom is missing from the steroid nucleus, making it a nor-steroid. The compound also has a trien system, which is a series of three conjugated double bonds, located at positions 2, 5(10), and 9(11). The "14,17a-dion" ending indicates the presence of two carbonyl groups (C=O) at the 14 and 17a positions. 3-Methoxy-8,14-seco-19-nor-homoandrosta-2,5(10),9(11)-trien-14,17a-dion is of interest in the field of organic chemistry and may have potential applications in pharmaceuticals or as a research tool in the study of steroidal compounds.
The CAS Registry Mumber 1425-25-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,2 and 5 respectively; the second part has 2 digits, 2 and 5 respectively. Calculate Digit Verification of CAS Registry Number 1425-25: (6*1)+(5*4)+(4*2)+(3*5)+(2*2)+(1*5)=58 58 % 10 = 8 So 1425-25-8 is a valid CAS Registry Number.
