166896-63-5 Usage
Uses
Used in Pharmaceutical Industry:3-Oxo-4-azaandrosta-1,5,7-triene-17-carboxylic Acid Methyl Ester is used as a key intermediate in the synthesis of Finasteride (F342000) for its role as an inhibitor of 5α-reductase. This enzyme is responsible for converting testosterone to the more potent androgen, 5α-dihydrotestosterone, which is associated with conditions such as benign prostatic hyperplasia (BPH) and androgenetic alopecia (male pattern hair loss). By inhibiting this enzyme, Finasteride helps to reduce the levels of 5α-dihydrotestosterone, providing relief from the symptoms of these conditions.
Check Digit Verification of cas no
The CAS Registry Mumber 166896-63-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,6,8,9 and 6 respectively; the second part has 2 digits, 6 and 3 respectively.Calculate Digit Verification of CAS Registry Number 166896-63:
(8*1)+(7*6)+(6*6)+(5*8)+(4*9)+(3*6)+(2*6)+(1*3)=195
195 % 10 = 5
So 166896-63-5 is a valid CAS Registry Number.
