759-21-7 Usage
General Description
2-Cyano-3-methylbut-2-enoic acid, also known as cyanoacetone, is a chemical compound with the molecular formula C6H9NO2. It is a colorless, flammable liquid with a sharp, pungent odor. It is mainly used in the production of pharmaceuticals, dyes, and other organic compounds. Cyanoacetone is also an important intermediate in the synthesis of various chemical products, including pesticides, plasticizers, and rubber chemicals. It is a highly reactive compound and should be handled and stored with care due to its potential hazards, including flammability and toxicity.
Check Digit Verification of cas no
The CAS Registry Mumber 759-21-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,5 and 9 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 759-21:
(5*7)+(4*5)+(3*9)+(2*2)+(1*1)=87
87 % 10 = 7
So 759-21-7 is a valid CAS Registry Number.

CO2 absorbing cost-effective ionic liquid for synthesis of commercially important alpha cyanoacrylic acids: A safe process for activation of cyanoacetic acid
Sharma, Yogesh O.,Degani, Mariam S.
experimental part, p. 526 - 530 (2010/04/23)
Cost-effective and carbon dioxide absorbing ionic liquid, tri-(2-hydroxyethyl) ammonium acetate, was shown to perform multiple roles in Knoevenagel condensation. It acted as an environmentally benign solvent, as an activating catalyst for the less reactive cyanoacetic acid and also as a risk reduction medium for the unevenly generated large amount of CO2 gas for large scale reactions. The reaction was scaled up for multi-gram synthesis of commercially important alpha cyanoacrylic acids.
