5514-35-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5514-35-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,5,1 and 4 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 5514-35:
(6*5)+(5*5)+(4*1)+(3*4)+(2*3)+(1*5)=82
82 % 10 = 2
So 5514-35-2 is a valid CAS Registry Number.

Kinetics and mechanism of the pudovik reaction in the azomethine series: II.1 Hydrolysis and catalysis in the reaction of dialkyl phosphites with benzalaniline

Sobanov,Zolotukhin,Galkin,Mostovaya,Cherkasov,Pudovik

, p. 871 - 876 (2007/10/03)

A 31P NMR study show that diisopropyl phosphite and benzalaniline do not react with each other as individual components. Adduct formation is made possible by partial hydrolysis of the dialkyl phosphite.

Photosolvolysis of O,O,S-Trimethyl Phosphorodithioate. Evidence for an SN1(P) Mechanism

Benschop, Hendrik P.,Konings, Cornelis A. G.,Platenburg, Dominique H. J. M.,Deen, Rudolf

, p. 370 - 372 (2007/10/02)

Irradiation (254 nm) of (MeO)2P(S)SMe in ROH yields mainly (66 percent, R = Pri) the ionic photosolvolysis product (MeO)2P(S)OR with very low capture ratio 1.9 +/- 0.4 for R = Me vs.R = Pri under competitive photosolvolysis conditions, whereas irradiation in e.g. tetrahydrofuran and CH2Cl2 gives free-radical products, suggesting that the photoreactions proceed by way of an 'intimate radical-ion pair.'
