It is commonly used in the manufacturing of perfumes and flavorings, and also has applications in the production of pharmaceuticals and organic synthesis. 2,4-Heptadienal, 2-methyl-6-oxo- (9CI) is considered to have low toxicity, but further research is needed to fully understand its potential health effects and environmental impact.

Check Digit Verification of cas no

The CAS Registry Mumber 195991-40-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,5,9,9 and 1 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 195991-40:
(8*1)+(7*9)+(6*5)+(5*9)+(4*9)+(3*1)+(2*4)+(1*0)=193
193 % 10 = 3
So 195991-40-3 is a valid CAS Registry Number.

Synthesis of Polyene Bioactive Natural Products: FR252921 and Vitamin A

Beeralingappa, Nagabhushana C.,Dethe, Dattatraya H.,Kumar, Vimlesh,Mishra, Kunj B.,Nirpal, Appasaheb K.

supporting information, (2022/03/31)

A formal synthesis of FR252921, a potent macrocyclic immunosuppressive agent, and a six-step synthesis of vitamin A have been demonstrated. The application of a ruthenium-catalyzed step-economic and environmentally benign strategy for the highly stereo- and chemoselective construction of valuable polyene motifs of FR252921 and vitamin A highlights the syntheses. The key features for the synthesis FR252921 include preparation of the triene moiety followed by two consecutive peptide couplings of the three fragments.

Mixed peroxides from the chloroperoxidase-catalyzed oxidation of conjugated dienoic esters with a trisubstituted terminal double bond

Bougioukou, Despina J.,Smonou, Ioulia

, p. 4511 - 4514 (2007/10/03)

The chloroperoxidase (CPO)-catalyzed oxidations of conjugated dienoic esters with a trisubstituted terminal double bond were studied by using tert-butyl hydroperoxide as the terminal oxidant. Most of the substrates gave disubstituted mixed peroxides as the major products.
