(1S,4S)-thujan-3-one-(2,4-dinitro-phenylhydrazone) and (+)-isothujone-(2,4-dinitro-phenylhydrazone) are two distinct chemical compounds derived from thujan-3-one and isothujone, respectively. These compounds are formed by the reaction of thujan-3-one and isothujone with 2,4-dinitrophenylhydrazine, resulting in the formation of hydrazone derivatives. The (1S,4S)-thujan-3-one-(2,4-dinitro-phenylhydrazone) is characterized by its specific stereochemistry, with the 1S and 4S configurations, while (+)-isothujone-(2,4-dinitro-phenylhydrazone) is the (+) enantiomer of isothujone's hydrazone derivative. These compounds are of interest in organic chemistry and may have applications in the synthesis of complex molecules or as analytical tools in chemical research.
The CAS Registry Mumber 2553-61-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,5 and 3 respectively; the second part has 2 digits, 6 and 1 respectively. Calculate Digit Verification of CAS Registry Number 2553-61: (6*2)+(5*5)+(4*5)+(3*3)+(2*6)+(1*1)=79 79 % 10 = 9 So 2553-61-9 is a valid CAS Registry Number.
