(3S,8S,9S,10R,13S,14S,17S)-17-[(R)-1-(2-Hydroxy-ethoxy)-ethyl]-10,13-dimethyl-2,3,4,7,8,9,10,11,12,13,14,15,16,17-tetradecahydro-1H-cyclopenta[a]phenanthren-3-ol is an example of the intricate and diverse structures found in organic chemistry, with potential applications in pharmaceuticals or other chemical industries.
The CAS Registry Mumber 1818-91-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,1 and 8 respectively; the second part has 2 digits, 9 and 1 respectively. Calculate Digit Verification of CAS Registry Number 1818-91: (6*1)+(5*8)+(4*1)+(3*8)+(2*9)+(1*1)=93 93 % 10 = 3 So 1818-91-3 is a valid CAS Registry Number.
