5β,17α-19-Norpregn-20-yn-3β,17-diol is a steroidal compound derived from the naturally occurring hormone pregnenolone. It is characterized by the presence of a triple bond at the 20th carbon position and the absence of the 19th carbon atom, which distinguishes it from its parent compound. This molecule exhibits a unique structure with a 3β-hydroxyl group and a 17α-hydroxyl group, which are crucial for its biological activity. It is of interest in the field of pharmaceuticals and biochemistry due to its potential applications in the development of drugs targeting various medical conditions, such as hormonal imbalances and certain types of cancer. The specific properties and effects of 5β,17α-19-norpregn-20-yn-3β,17-diol are subject to ongoing research, as its interactions with the human body and potential therapeutic uses are still being explored.

Check Digit Verification of cas no

The CAS Registry Mumber 1093-46-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,9 and 3 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1093-46:
(6*1)+(5*0)+(4*9)+(3*3)+(2*4)+(1*6)=65
65 % 10 = 5
So 1093-46-5 is a valid CAS Registry Number.
