16900-65-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 16900-65-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,9,0 and 0 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 16900-65:
(7*1)+(6*6)+(5*9)+(4*0)+(3*0)+(2*6)+(1*5)=105
105 % 10 = 5
So 16900-65-5 is a valid CAS Registry Number.

Benzannulation through Ruthenium(0)-Catalyzed Transfer Hydrogenative Cycloaddition: Precision Synthesis and Photophysical Characterization of Soluble Diindenoperylenes

Suravarapu, Sankar Rao,Parvathaneni, Sai Prathima,Bender, Jon A.,Roberts, Sean T.,Krische, Michael J.

, p. 7504 - 7510 (2020)

The first application of ruthenium(0)-catalyzed 1,2-dione-diyne [2+2+2] cycloaddition to PAH construction is achieved by the precision synthesis of soluble diindenoperylenes (DIPs), the electronic structures of which were investigated using steady-state a

Iridium- and rhodium-catalyzed [2+2+2] cycloadditions of diynes with maleimide: A new synthetic route to highly substituted phthalimides

Alvarez, Leonardo X.,Bessières, Bernard,Einhorn, Jacques

experimental part, p. 1376 - 1380 (2009/04/06)

The [2+2+2] cycloaddition of maleimide with α,ω-diynes in the presence of [IrCl(cod)]2 or [RhCl(cod)]2 and DPPE gives cyclohexadiene derivatives which are readily aromatized with DDQ or MnO 2. This two-step procedure gives

Cyclisation of Acetylenecarboxylic Acid. Synthesis of γ-Methylenebutyrolactones

Yamamato, Makoto

, p. 582 - 587 (2007/10/02)

Various γ-exo-methylenebutyrolactones have been synthesized in excellent yield by the cyclisation of acetylenecarboxylic acids in the presence of a catalytic amount of mercury(II) oxide.Cyclisation of terminal acetylene compounds proceeded regioselectively to give γ-exo-methylenebutyrolactones as the sole product.Disubstituted acetylenes also gave the (Z)-configurational enol lactone, but small amounts of an (E)-isomer of a γ-exo-enol lactone and a δ-lactone (α-pyrone) were also formed.Spectral properties and stereochemistry of the exo-enol lactones are also discussed.
