3β-hydroxy-17,17a-seco-D-homo-androstene-(5)-dioic acid-(17,17a) is a complex organic compound with a unique chemical structure. It is derived from the androstene family of steroids, characterized by the presence of a 5-membered ring and a 17,17a double bond. The compound features a hydroxyl group at the 3β position and a carboxylic acid group at both the 17 and 17a positions, which contribute to its acidic properties. This molecule is a secosteroid, meaning it has undergone a ring contraction, and is a D-homo derivative, indicating that it has an additional carbon atom in the steroid nucleus compared to the parent compound. The specific arrangement of functional groups and the seco structure give 3β-hydroxy-17.17a-seco-D-homo-androstene-(5)-dioic acid-(17.17a) unique chemical and biological properties, which may have potential applications in pharmaceuticals or chemical research.
The CAS Registry Mumber 2099-39-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,0,9 and 9 respectively; the second part has 2 digits, 3 and 9 respectively. Calculate Digit Verification of CAS Registry Number 2099-39: (6*2)+(5*0)+(4*9)+(3*9)+(2*3)+(1*9)=90 90 % 10 = 0 So 2099-39-0 is a valid CAS Registry Number.
