11β-hydroxy-9-thiocyanato-androst-4-ene-3,17-dione is a complex organic compound with the molecular formula C21H27NO2S. It is a derivative of androst-4-ene-3,17-dione, a steroid hormone, with a hydroxyl group at the 11β position and a thiocyanate group at the 9 position. 11β-hydroxy-9-thiocyanato-androst-4-ene-3,17-dione is characterized by its unique structure, which includes a four-ring steroid nucleus with a double bond between carbons 4 and 5, and a ketone group at the 3 and 17 positions. The presence of the thiocyanate group introduces a sulfur atom and a cyanide group, which can significantly alter the chemical properties and potential applications of the molecule. 11β-hydroxy-9-thiocyanato-androst-4-ene-3,17-dione may be of interest in the field of organic chemistry, particularly in the study of steroidal compounds and their derivatives, as well as in pharmaceutical research for potential therapeutic applications.
The CAS Registry Mumber 1166-72-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,6 and 6 respectively; the second part has 2 digits, 7 and 2 respectively. Calculate Digit Verification of CAS Registry Number 1166-72: (6*1)+(5*1)+(4*6)+(3*6)+(2*7)+(1*2)=69 69 % 10 = 9 So 1166-72-9 is a valid CAS Registry Number.
