71691-29-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 71691-29-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,6,9 and 1 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 71691-29:
(7*7)+(6*1)+(5*6)+(4*9)+(3*1)+(2*2)+(1*9)=137
137 % 10 = 7
So 71691-29-7 is a valid CAS Registry Number.

Inhibition of the enzymes in the leukotriene and prostaglandin pathways in inflammation by 3-aryl isocoumarins

Ramanan, Meera,Sinha, Shweta,Sudarshan, Kasireddy,Aidhen, Indrapal Singh,Doble, Mukesh

, p. 428 - 434 (2016)

The biosynthesis of leukotrienes in one of the arachidonic acid pathways and PGE2in the other by 5-LOX and mPGES1 respectively, play pivotal roles in augmenting inflammatory responses. PGE2is known to participate in cancer pathologic

Synthesis of 3-arylisocoumarins by using acyl anion chemistry and synthesis of thunberginol A and cajanolactone A

Sudarshan, Kasireddy,Manna, Manash Kumar,Aidhen, Indrapal Singh

, p. 1797 - 1803 (2015/05/27)

A new strategy for the synthesis of 3-arylisocoumarins and 8-hydroxy-3-arylisocoumarins was investigated by using acyl anion chemistry for the initial C-C bond formation. The obtained keto esters and keto lactones as intermediates underwent based-promoted intramolecular cyclization to afford 3-arylisocoumarins in good yields. The developed methodology was applied for the synthesis of the important natural products thunberginol A and cajanolactone A.
