18-Hydroxypregn-4-ene-3,20-dione (18<*>20) hemiketal-20-hydroperoxide acetate is a complex organic compound with the molecular formula C23H32O6. It is a derivative of pregnane, a steroid with a four-ring structure. The compound is characterized by the presence of a hydroxyl group at the 18th carbon, a ketone group at both the 3rd and 20th carbons, and a hemiketal structure between the 18th and 20th carbons. The 20-hydroperoxide group is a peroxide derivative, which is a type of reactive oxygen species. 18-hydroxypregn-4-ene-3,20-dione(18<*>20) hemiketal-20-hydroperoxide acetate is further modified by the acetate group, which is an ester derived from acetic acid. It is important to note that the compound's structure and properties can make it reactive and potentially unstable, which is a common characteristic of steroidal compounds with peroxide functionalities. Such compounds are often found in the context of pharmaceuticals and biochemistry, where they may have specific biological activities or be used as intermediates in the synthesis of other compounds.
The CAS Registry Mumber 1923-10-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,2 and 3 respectively; the second part has 2 digits, 1 and 0 respectively. Calculate Digit Verification of CAS Registry Number 1923-10: (6*1)+(5*9)+(4*2)+(3*3)+(2*1)+(1*0)=70 70 % 10 = 0 So 1923-10-0 is a valid CAS Registry Number.
