3-acetoxy-ergosta-3,5,7,9(11),22t-pentaene is a complex organic compound belonging to the steroid family, specifically a triterpene. It is characterized by a unique carbon skeleton with five double bonds and a 3-acetoxy group. 3-acetoxy-ergosta-3,5,7,9(11),22t-pentaene is derived from ergostane, a naturally occurring triterpene alcohol, and is known for its potential biological activities, such as anti-inflammatory and immunosuppressive properties. The presence of the acetoxy group at the 3-position and the trans configuration at the 22nd carbon (indicated by the t) are key structural features that influence its reactivity and potential applications in pharmaceutical research.
The CAS Registry Mumber 6167-95-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,1,6 and 7 respectively; the second part has 2 digits, 9 and 5 respectively. Calculate Digit Verification of CAS Registry Number 6167-95: (6*6)+(5*1)+(4*6)+(3*7)+(2*9)+(1*5)=109 109 % 10 = 9 So 6167-95-9 is a valid CAS Registry Number.
