2-Heptynenitrile, also known as 2-heptenenitrile or 2-heptyl nitrile, is an organic compound with the chemical formula C7H11N. It is a colorless liquid with a strong, pungent odor and is characterized by a conjugated diene system, which consists of a triple bond (C≡C) adjacent to a double bond (C=C). This molecule is derived from heptene, a seven-carbon alkene, with a nitrile group (-CN) attached to the second carbon atom. 2-Heptynenitrile is used in the synthesis of various chemicals, pharmaceuticals, and agrochemicals, and it can also be found as an intermediate in the production of polymers and other industrial chemicals. Due to its reactive nature, it is important to handle 2-heptynenitrile with care, as it can be toxic and harmful to human health and the environment.
The CAS Registry Mumber 1972-96-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,7 and 2 respectively; the second part has 2 digits, 9 and 6 respectively. Calculate Digit Verification of CAS Registry Number 1972-96: (6*1)+(5*9)+(4*7)+(3*2)+(2*9)+(1*6)=109 109 % 10 = 9 So 1972-96-9 is a valid CAS Registry Number.
