90036-77-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 90036-77-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,0,3 and 6 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 90036-77:
(7*9)+(6*0)+(5*0)+(4*3)+(3*6)+(2*7)+(1*7)=114
114 % 10 = 4
So 90036-77-4 is a valid CAS Registry Number.

Synthesis of 2-Methylene-1,3-dioxygenated Cyclopentanes and Cyclopentenes

Chantarasiri, Nuanphun,Dinprasert, Pranee,Thebtaranonth, Chachanat,Thebtaranonth, Yodhathai,Yenjai, Chavi

, p. 286 - 288 (2007/10/02)

Antracene adducts (4)-(6) are synthesized via a convenient general synthesis and subjected to a retro Diels-Alder reaction to furnish the corresponding 2-methylene-1,3-dioxygenated cyclopentenes and cyclopentanes (1)-(3) via either flash vaccum pyrolysis or room temperature silica gel-catalysed decomposition.

Acid catalysis of the retro-diels alder reaction. Formation and electrophilic reactivity of 2-methylene-1,3-cyclopentanedione.

Bunnelle, William H.,Randall Shangraw

, p. 2005 - 2011 (2007/10/02)

The acid mediated decomposition of the Diels-A1der adduct of 1,3-cyclopentanedione with anthracene was studied. An extremely facile, acid catalyzed retro-Diels-Alder fragmentation produces 2-methylene-1,3-cyclopentanedione, which undergoes twofold electrophilic substitution on the cognate anthracene nucleus.
