The compound also features a pivalate ester group, which is derived from pivalic acid, a type of carboxylic acid. The stereochemistry of the molecule is defined by the R, S, and S configurations at the 8th, 9th, 13th, and 14th positions, respectively. (8R,9S,13S,14S)-13-methyl-17-oxo-7,8,9,11,12,13,14,15,16,17-decahydro-6H-cyclopenta[a]phenanthren-3-yl pivalate is likely to be found in specialized chemical research or pharmaceutical applications due to its complex structure and potential biological activity.
The CAS Registry Mumber 4003-22-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,0,0 and 3 respectively; the second part has 2 digits, 2 and 2 respectively. Calculate Digit Verification of CAS Registry Number 4003-22: (6*4)+(5*0)+(4*0)+(3*3)+(2*2)+(1*2)=39 39 % 10 = 9 So 4003-22-9 is a valid CAS Registry Number.
