19,19-Difluorotestosterone (19,19-DFT) is a synthetic derivative of testosterone, a naturally occurring androgen hormone. It is characterized by the presence of two fluorine atoms at the 19th carbon position, which significantly alters its chemical properties and biological activity. This modification enhances its resistance to metabolism by enzymes, such as 5α-reductase, which is responsible for converting testosterone into dihydrotestosterone (DHT). As a result, 19,19-DFT exhibits a longer half-life and increased potency compared to natural testosterone. It is primarily used in medical research to study the effects of androgens on various physiological processes and has potential applications in the treatment of conditions related to androgen deficiency. However, it is important to note that 19,19-DFT is not approved for human use and is considered an investigational drug.

Check Digit Verification of cas no

The CAS Registry Mumber 7764-47-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,6 and 4 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 7764-47:
(6*7)+(5*7)+(4*6)+(3*4)+(2*4)+(1*7)=128
128 % 10 = 8
So 7764-47-8 is a valid CAS Registry Number.
