Check Digit Verification of cas no

The CAS Registry Mumber 289-68-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,8 and 9 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 289-68:
(5*2)+(4*8)+(3*9)+(2*6)+(1*8)=89
89 % 10 = 9
So 289-68-9 is a valid CAS Registry Number.

2-(Trimethylsilyl)-λ3-Phosphinine: Synthesis, Coordination Chemistry, and Reactivity

Habicht, Marija H.,Wossidlo, Friedrich,Bens, Tobias,Pidko, Evgeny A.,Müller, Christian

, p. 944 - 952 (2018)

The [4+2] cycloaddition reaction between 2-pyrone and Me3Si?C≡P gives the corresponding 2-(trimethylsilyl)-λ3-phosphinine in good yields as a rather air and moisture stable, colorless oil. Insight into the regioselectivity of the pericyclic reaction was obtained with the help of deuterium-labeling experiments. The silyl-phosphinine acts as a ligand for the preparation of a Cu(I) and the first crystallographically characterized phosphinine-Ag(I) complex. The title compound was further used as a starting material for an alternative preparation of the parent phosphinine C5H5P by means of protodesilylation with HCl. C5H5P reacts with CuBr?S(CH3)2 to give an infinite Cu(I)Br coordination polymer. DFT calculations shed light on the influence of the -Si(CH3)3 group on the electronic properties of the aromatic phosphorus heterocycle.

Reduction of λ5-Phosphinines

Savateev, Aleksandr,Vlasenko, Yurii,Shtil, Nataliya,Kostyuk, Aleksandr

, p. 628 - 632 (2016/03/01)

A convenient method to easily prepare parent λ3-phosphinine from easily accessible λ5-precursors was developed. A series of λ5-phosphinines bearing heteroatom substituents OMe, SMe, and/or NMe2 at the phosphorus

Synthesis of the Parent Phosphinine and Phosphaalkyne by Flash Thermolysis of Vinyldiallyl- and Triallyl-phosphine

Floch, Pascal Le,Mathey, Francois

, p. 1295 - 1296 (2007/10/02)

The parent phosphinine is obtained in ca. 40percent yield by thermolysis of vinyldiallylphosphine at 700 deg C at 10-3 Torr; under the same conditions, triallylphosphine mainly yields HCP which can be purified by trap-to-trap distillation.
