1,1-Dideuterio-2,2-difluoro-ethene is a halogenated hydrocarbon with the chemical formula C2D2F2. It is a structural isomer of ethene (ethylene), where two hydrogen atoms are replaced by deuterium atoms (2H) and two hydrogen atoms are replaced by fluorine atoms (F). 1,1-dideuterio-2,2-difluoro-ethene is a colorless, volatile liquid with a low boiling point, and it is relatively stable due to the presence of deuterium and fluorine atoms. The deuterium atoms increase the molecular weight and slightly alter the physical properties of the compound, while the fluorine atoms enhance the electronegativity and reactivity. 1,1-Dideuterio-2,2-difluoro-ethene has potential applications in chemical research, as a tracer in isotope studies, and as a precursor in the synthesis of other fluorinated compounds.
The CAS Registry Mumber 563-93-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,6 and 3 respectively; the second part has 2 digits, 9 and 3 respectively. Calculate Digit Verification of CAS Registry Number 563-93: (5*5)+(4*6)+(3*3)+(2*9)+(1*3)=79 79 % 10 = 9 So 563-93-9 is a valid CAS Registry Number.
