16α,17-Isopropylidenedioxy-pregna-4,9(11)-diene-3,20-dione is a complex steroidal compound characterized by its unique molecular structure. It features a pregnane core, which is a type of steroid with a four-ring structure. The compound is further defined by the presence of an isopropylidenedioxy group at the 16α and 17 positions, which introduces a methylene bridge between these two carbon atoms, and a double bond between carbons 4 and 9, with the 9(11) double bond indicating a conjugated diene system. Additionally, it has ketone functional groups at the 3 and 20 positions, which are carbonyl groups that can form hydrogen bonds and participate in various chemical reactions. 16α,17-isopropylidenedioxy-pregna-4,9(11)-diene-3,20-dione is of interest in the field of organic chemistry, particularly in the study of natural products and the development of pharmaceuticals, due to its potential biological activities and structural complexity.

2135-09-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 2135-09-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,3 and 5 respectively; the second part has 2 digits, 0 and 9 respectively.Calculate Digit Verification of CAS Registry Number 2135-09:
(6*2)+(5*1)+(4*3)+(3*5)+(2*0)+(1*9)=53
53 % 10 = 3
So 2135-09-3 is a valid CAS Registry Number.
