91533-23-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 91533-23-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,5,3 and 3 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 91533-23:
(7*9)+(6*1)+(5*5)+(4*3)+(3*3)+(2*2)+(1*3)=122
122 % 10 = 2
So 91533-23-2 is a valid CAS Registry Number.

Green procedure for the synthesis of phthalazino[2,3-b]phthalazine-5,7,12, 14-tetraones

Habibi, Davood,Mahmoudi, Nosratollah,Marvi, Omid

, p. 3165 - 3171 (2007)

Different novel phthalazino[2,3-b]phthalazine-5,7,12,14-tetraones were synthesized in a simple and environmentally benign method from the reaction of phthalic anhydrides with semicarbazide or thiosemicarbazide using montmorillonite K-10 clay as solid heterogeneous acidic catalyst and microwaves under solvent-free conditions in good yields and short reaction times. Products were characterized by the elemental analysis, IR, NMR, and mass spectrometry. Copyright Taylor & Francis Group, LLC.

Synthesis and Biological Activity Evaluation of Differently Substituted 1,4-Dioxo-3,4-dihydrophthalazine-2(1H)-carboxamides and -carbothioamides

Cardia,Distinto,Maccioni,Bonsignore,DeLogu

, p. 1011 - 1015 (2007/10/03)

Differently substituted phthalic anhydrides can react either with semicarbazide or thiosemicarbazide to give respectively 1,4-dioxo-3,4-dihydrophthalazine-2(1H)-carboxamides or 1,4-dioxo-3,4-dihydrophthalazine-2(1H)-carbothioamides under mild conditions and generally with good yields. These compounds have been tested in order to evaluate their anti-microbial activity. Furthermore a new synthetic pathway to phtha-lazino[2,3-b]phthalazine-5,7,12,14-tetraone has been devised.
