11α,21-Diacetoxy-17-hydroxy-9β,10α-pregn-4-en-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 distinguished by the presence of two acetoxy groups at the 11α and 21 positions, a hydroxyl group at the 17 position, and a double bond between carbons 4 and 5 of the pregnane ring. Additionally, it has a ketone group at the 3 position and a second ketone group at the 20 position, which together form a 3,20-dione structure. This specific arrangement of functional groups gives the compound its unique chemical properties and potential biological activities, which may be relevant in the fields of medicine and pharmacology.

Check Digit Verification of cas no

The CAS Registry Mumber 1178-91-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,7 and 8 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1178-91:
(6*1)+(5*1)+(4*7)+(3*8)+(2*9)+(1*1)=82
82 % 10 = 2
So 1178-91-2 is a valid CAS Registry Number.
