Diethylene glycol bis(allyl phthalate), also known as DEG-AP, is a chemical compound that belongs to the family of phthalate esters. It is formed by the reaction of diethylene glycol with phthalic anhydride and allyl alcohol, resulting in a colorless, viscous liquid with a molecular formula of C20H22O6. Diethylenglykol-bis-(allylphthalat) is widely used as a plasticizer in the production of flexible polyvinyl chloride (PVC) products, such as hoses, films, and cables, due to its excellent compatibility, low volatility, and resistance to extraction. DEG-AP also exhibits good thermal stability and resistance to UV radiation, making it suitable for applications where durability and flexibility are required. However, it is important to note that, like other phthalates, DEG-AP may have potential health and environmental concerns, and its use is regulated in certain applications to minimize exposure.

Check Digit Verification of cas no

The CAS Registry Mumber 4091-04-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,0,9 and 1 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 4091-04:
(6*4)+(5*0)+(4*9)+(3*1)+(2*0)+(1*4)=67
67 % 10 = 7
So 4091-04-7 is a valid CAS Registry Number.

Efficient synthesis of 19-31 membered macrocyclic tetralactones via ring closing metathesis in ionic liquids

Muthusamy, Sengodagounder,Azhagan, Datschnamoorthy

scheme or table, p. 8196 - 8202 (2010/11/02)

The ring closing metathesis reaction in the presence of Grubbs catalyst was demonstrated using several ionic liquids to synthesize a range of macrocyclic tetralactones having ring size of 19 to 31 membered with different spacers. The ionic liquid [mmim][PF6] was found to be an excellent solvent and the recovery of the catalyst was demonstrated. X-ray analysis of a representative macrocyclic tetralactone was also reported.
