821-60-3 Usage
General Description
1,3-Butadiene-1,4-dicarbonitrile, also known as Pandion, is a synthetic organic compound that is primarily used as a crosslinking agent in the production of acrylic resins. It is a colorless liquid with a pungent odor and is highly flammable. 1,3-Butadiene-1,4-dicarbonitrile is classified as a hazardous chemical and is considered a potential carcinogen, posing health risks to humans. Exposure to this chemical can occur through inhalation, ingestion, or skin contact. Its toxicity and potential environmental impact make it a highly regulated substance, requiring careful handling and disposal to minimize its negative effects.
Check Digit Verification of cas no
The CAS Registry Mumber 821-60-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,2 and 1 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 821-60:
(5*8)+(4*2)+(3*1)+(2*6)+(1*0)=63
63 % 10 = 3
So 821-60-3 is a valid CAS Registry Number.

Improvement of catalyst activity in the Ru-catalyzed dimerization of acrylonitrile by using diphenyl ether as a solvent
Kashiwagi, Kohichi,Sugise, Ryoji,Shimakawa, Toshihiro,Matuura, Tunao
, p. 1384 - 1385 (2008/03/18)
For the catalyst system of ruthenium and carboxylic acid, which is useful for the efficient tail-to-tail dimerization of acrylonitrile, the TON increases as the ruthenium catalyst concentration is decreased. Furthermore, the addition of aromatic solvents of equal volume to that of acrylonitrile improves the catalyst activity. Especially, the use of diphenyl ether leads to a 1.7 time improvement of the TON. Copyright
