Check Digit Verification of cas no
The CAS Registry Mumber 5198-68-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,9 and 8 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 5198-68:
(6*5)+(5*1)+(4*9)+(3*8)+(2*6)+(1*8)=115
115 % 10 = 5
So 5198-68-5 is a valid CAS Registry Number.

Metal-Free Br?nsted Acid-Catalyzed Rearrangement of δ-Hydroxyalkynones to 2,3-Dihydro-4 H-pyran-4-ones: Total Synthesis of Obolactone and a Catechol Pyran Isolated from Plectranthus sylvestris

A metal-free, Br?nsted acid, pTsOH-catalyzed intramolecular rearrangement of δ-hydroxyalkynones to substituted 2,3-dihydro-4H-pyran-4-ones was developed. The rearrangement occurs with high regioselectivity under mild and open-air conditions. The scope of work was illustrated by synthesizing an array of aliphatic and aromatic substituted 2,3-dihydro-4H-pyran-4-ones in up to 96% yield, 100% atom economy, and complete regioselectivity. Some of the dihydropyranones are utilized for vinylic halogenations and to complete the total synthesis of bioactive natural products, obolactone and a catechol pyran isolated from Plectranthus sylvestris (Labiatae).
