"Cis, cis-(2,4-Dinitrophenyl)-dithio-butadien" is a chemical compound with the formula C10H8N4O4S2. It is a derivative of butadiene, a conjugated diene, with two nitro groups (-NO2) attached to the phenyl ring and two sulfur atoms (S) forming a dithioether bridge. The "cis, cis" configuration indicates that both double bonds in the butadiene are in the cis configuration, meaning the substituents are on the same side of the molecule. cis, cis-(2,4-Dinitrophenyl)-dithio-butadien is known for its reactivity and can be used in various chemical reactions, particularly in the synthesis of other organic compounds. It is also of interest in the study of conjugated systems and their electronic properties.
The CAS Registry Mumber 4816-71-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,1 and 6 respectively; the second part has 2 digits, 7 and 1 respectively. Calculate Digit Verification of CAS Registry Number 4816-71: (6*4)+(5*8)+(4*1)+(3*6)+(2*7)+(1*1)=101 101 % 10 = 1 So 4816-71-1 is a valid CAS Registry Number.
