1051-35-0

3-cycloethylenedioxy-pregn-5-ene-20-one, also known as 3-cycloethylenedioxyprogesterone, is a synthetic steroid derived from the naturally occurring hormone progesterone. This chemical compound features a cycloethylenedioxy group at the 3-position and a ketone group at the 20-position, which differentiates it from its parent compound. It is used in pharmaceutical applications, particularly in the development of contraceptives and hormone replacement therapies, due to its ability to modulate hormonal activity. The specific structural modifications in this compound contribute to its unique pharmacological properties, making it a subject of interest in medical research and drug development.

1051-35-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1051-35-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,5 and 1 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1051-35:
(6*1)+(5*0)+(4*5)+(3*1)+(2*3)+(1*5)=40
40 % 10 = 0
So 1051-35-0 is a valid CAS Registry Number.

CHEMOSELECTIVE ETHYLENE ACETALIZATION OF α,β-UNSATURATED vis-a-vis SATURATED CARBONYL GROUPS

Nitz, Theodore J.,Paquette, Leo A.

, p. 3047 - 3050 (1984)

The difficulties which in the past have precluded controlled acetalization of an α,β-unsaturated ketone functionality in the presence of a saturated carbonyl group can be overcome simply by making recourse to 2,4,6-collidinium p-toluenesulfonate as catalyst.
