(20Ξ)-17,20;20,21-bis-methanediyldioxy-16α-methyl-pregn-4-ene-2,3,11-trione 2-oxime 3-phenylhydrazone is a complex organic compound with a molecular formula of C31H39N3O6. It is a derivative of pregnane, a steroid with a four-ring structure. The compound features two oxime groups, one at the 2-position and another at the 3-position, which are connected to the pregnane core through a phenylhydrazone linkage. The presence of two methanediyldioxy bridges at the 17,20 and 20,21 positions, along with a methyl group at the 16α position, further characterizes the structure. (20Ξ)-17,20;20,21-bis-methanediyldioxy-16α-methyl-pregn-4-ene-2,3,11-trione 2-oxime 3-phenylhydrazone is of interest in the field of organic chemistry and may have potential applications in pharmaceutical research due to its unique structure and functional groups.
The CAS Registry Mumber 3386-81-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,3,8 and 6 respectively; the second part has 2 digits, 8 and 1 respectively. Calculate Digit Verification of CAS Registry Number 3386-81: (6*3)+(5*3)+(4*8)+(3*6)+(2*8)+(1*1)=100 100 % 10 = 0 So 3386-81-0 is a valid CAS Registry Number.
