Pregn-5,17(20)-dien-21-oic acid, 4,4-difluoro-3,11-dioxo-, methyl ester, 3-[(2,4-dinitrophenyl)hydrazone], (?,Z)- (8CI) is a complex organic compound with the molecular formula C24H25F2N4O6. It is a derivative of pregnane, a steroid with a 21-carbon skeleton, and features a 4,4-difluoro substitution on the 3-oxo group, a methyl ester at the 21-position, and a 2,4-dinitrophenylhydrazone group at the 3-position. Pregna-5,17(20)-dien-21-oicacid, 4,4-difluoro-3,11-dioxo-, methyl ester, 3-[(2,4-dinitrophenyl)hydrazone],(?,Z)- (8CI) is characterized by its double bond configuration, which can exist in either the (E) or (Z) form, indicating the geometric arrangement of the double bond. It is an important intermediate in the synthesis of various steroidal compounds and has potential applications in pharmaceutical research due to its structural diversity and chemical reactivity.
The CAS Registry Mumber 5179-62-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,7 and 9 respectively; the second part has 2 digits, 6 and 2 respectively. Calculate Digit Verification of CAS Registry Number 5179-62: (6*5)+(5*1)+(4*7)+(3*9)+(2*6)+(1*2)=104 104 % 10 = 4 So 5179-62-4 is a valid CAS Registry Number.
