Heneicosanedinitrile, also known as 21-dicyanohenicosane, is an organic compound with the chemical formula C21H38N2. It is a long-chain nitrile, consisting of a 21-carbon alkane with two cyano groups (-CN) attached to the terminal carbon atoms. This molecule is characterized by its linear structure and the presence of two triple bonds within the cyano groups, which contribute to its chemical reactivity. Heneicosanedinitrile is a colorless, crystalline solid with a melting point of approximately 40°C. It is insoluble in water but soluble in organic solvents such as ethanol and acetone. Due to its unique structure, heneicosanedinitrile has potential applications in the synthesis of various chemicals, materials, and pharmaceuticals, as well as in the field of polymer chemistry.
The CAS Registry Mumber 6703-83-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,7,0 and 3 respectively; the second part has 2 digits, 8 and 3 respectively. Calculate Digit Verification of CAS Registry Number 6703-83: (6*6)+(5*7)+(4*0)+(3*3)+(2*8)+(1*3)=99 99 % 10 = 9 So 6703-83-9 is a valid CAS Registry Number.
