D-Δ¹-5β-pregnen-20-one, also known as pregnenolone, is a steroid hormone and a key intermediate in the synthesis of other steroid hormones, such as cortisol, aldosterone, and sex hormones like testosterone and estrogen. It is produced in the adrenal glands and gonads and plays a crucial role in various physiological processes, including stress response, immune function, and brain function. Pregnenolone is also considered a neurosteroid, as it can modulate the function of the central nervous system, potentially affecting mood, cognition, and memory. Its chemical structure is characterized by a pregnane nucleus with a Δ¹ double bond and a 20-ketone group, and it is a precursor in the biosynthesis of other important steroids, making it a significant compound in endocrinology and pharmacology.

Check Digit Verification of cas no

The CAS Registry Mumber 2426-34-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,4,2 and 6 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 2426-34:
(6*2)+(5*4)+(4*2)+(3*6)+(2*3)+(1*4)=68
68 % 10 = 8
So 2426-34-8 is a valid CAS Registry Number.
