General Description
17-hydroxy-1,5:1,9-dicyclo-9,10-secoestran-4-one is a chemical compound that belongs to the class of dicyclo compounds and secoestran hormones. It is a derivative of the hormone estradiol, which plays a critical role in the regulation of the female reproductive system. The presence of a hydroxy group and a dicyclo structure in the compound gives it unique properties and potential biological activities. This chemical may have applications in pharmaceutical research and development, particularly in the study and modulation of hormonal pathways and related diseases. Further research is needed to fully understand the potential uses and effects of 17-hydroxy-1,5:1,9-dicyclo-9,10-secoestran-4-one.
Check Digit Verification of cas no
The CAS Registry Mumber 21003-06-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,0,0 and 3 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 21003-06:
(7*2)+(6*1)+(5*0)+(4*0)+(3*3)+(2*0)+(1*6)=35
35 % 10 = 5
So 21003-06-5 is a valid CAS Registry Number.

PHOTOLYSIS OF 3-OXO-Δ5(10)-STEROIDS IN ALCOHOLIC SOLVENTS AND IN THE SOLID PHASE
Williams, John R.,Abdel-Magid, Ahmed
, p. 1675 - 1678 (2007/10/02)
Irradiation of the β,γ-unsaturated ketone 1a in alcoholic solvents afforded the 1,2 and 1,3-acyl shift products 2a and 3 respectively.The cyclobutanone 3 underwent further photochemistry incorporating a molecule of solvent and affording the ring expanded cyclic acetal 6.Solid phase irradiation of 1a yielded 2a and 3 but 1b was photostable.
