5β-Androstane-3,17-dione-bis-(2,4-dinitro-phenylhydrazone) is a chemical compound derived from the steroid androstane, specifically androstane-3,17-dione. 5β-androstane-3,17-dione-bis-(2,4-dinitro-phenylhydrazone) is formed by the reaction of androstane-3,17-dione with 2,4-dinitrophenylhydrazine, resulting in the formation of two hydrazone groups. The presence of these hydrazone groups allows for the detection and quantification of androstane-3,17-dione in various analytical techniques, such as spectrophotometry and chromatography. 5β-androstane-3,17-dione-bis-(2,4-dinitro-phenylhydrazone) is of interest in the field of steroid chemistry and can be used as a reference standard for the analysis of androstane-3,17-dione in biological samples.
The CAS Registry Mumber 4680-87-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,8 and 0 respectively; the second part has 2 digits, 8 and 7 respectively. Calculate Digit Verification of CAS Registry Number 4680-87: (6*4)+(5*6)+(4*8)+(3*0)+(2*8)+(1*7)=109 109 % 10 = 9 So 4680-87-9 is a valid CAS Registry Number.
