566-63-2 Usage
Uses
17-epi-Pregnenolone is an impurity of Pregnenolone(P712200). Pregnenolone is a steroid hormone involved in the steroidogenesis of progesterone, mineralocorticoids, glucocorticoids, androgens, and estrogens. As such it is a prohormone. Pregnenolone is a GABAA antagonist and increases neurogenesis in the hippocampus. It is a modulator of cytochrome P 450-3A.
Check Digit Verification of cas no
The CAS Registry Mumber 566-63-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,6 and 6 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 566-63:
(5*5)+(4*6)+(3*6)+(2*6)+(1*3)=82
82 % 10 = 2
So 566-63-2 is a valid CAS Registry Number.

Proline-promoted dehydroxylation of α-ketols
Mostinski, Yelena,Lankri, David,Konovalov, Yana,Nataf, Riva,Tsvelikhovsky, Dmitry

A new single-step proline-potassium acetate promoted reductive dehydroxylation of α-ketols is reported. We introduce the unexplored reactivity of proline and, for the first time, reveal its ability to function as a reducing agent. The developed metal-free and open-flask operation generally results in good yields. Our protocol allows the challenging selective dehydroxylation of hydroxyketones without affecting other functional groups.
