(10α,23E)-2β,16α-Bis(acetyloxy)-20,25-dihydroxy-9β-methyl-19-norlanosta-5,23-diene-3,11,22-trione is a complex organic compound belonging to the class of triterpenoids, specifically a derivative of lanostane. It features a unique carbon skeleton with 30 carbon atoms, characterized by the presence of three ketone groups (trione) at positions 3, 11, and 22, and two hydroxyl groups at positions 20 and 25. The molecule also contains two acetyloxy groups at positions 2 and 16, which are esterified with acetic acid. The 9β-methyl group and the 19-nor structure indicate the presence of a methyl group at the 9β position and the absence of a carbon atom at position 19, respectively. (10α,23E)-2β,16α-Bis(acetyloxy)-20,25-dihydroxy-9β-methyl-19-norlanosta-5,23-diene-3,11,22-trione exhibits a 10α,23E configuration, which refers to the specific arrangement of double bonds and hydroxyl groups in the molecule. Due to its intricate structure and potential biological activities, (10α,23E)-2β,16α-Bis(acetyloxy)-20,25-dihydroxy-9β-methyl-19-norlanosta-5,23-diene-3,11,22-trione is of interest in the field of natural product chemistry and may have applications in pharmaceutical research.

3520-11-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3520-11-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,5,2 and 0 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 3520-11:
(6*3)+(5*5)+(4*2)+(3*0)+(2*1)+(1*1)=54
54 % 10 = 4
So 3520-11-4 is a valid CAS Registry Number.
