Check Digit Verification of cas no

The CAS Registry Mumber 4559-70-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,5,5 and 9 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4559-70:
(6*4)+(5*5)+(4*5)+(3*9)+(2*7)+(1*0)=110
110 % 10 = 0
So 4559-70-0 is a valid CAS Registry Number.

Metal-Free, Visible Light-Photocatalyzed Synthesis of Benzo[b]phosphole Oxides: Synthetic and Mechanistic Investigations

, p. 7436 - 7441 (2016)

Highly functionalized benzo[b]phosphole oxides were synthesized from reactions of arylphosphine oxides with alkynes under photocatalytic conditions by using eosin Y as the catalyst and N-ethoxy-2-methylpyridinium tetrafluoroborate as the oxidant. The reac

Extraction and coordination behavior of diphenyl hydrogen phosphine oxide towards actinides

Extraction behavior of some selected actinides like U(VI), Th(IV), and Am(III) was investigated with three different H-phosphine oxides, viz. diphenyl hydrogen phosphine oxide (DPhPO), dihexyl hydrogen phosphine oxide (DHePO) and diphenyl phosphite (DPP).

Photochemistry and Photophysics of (1-Naphthoyl)diphenylphosphine Oxide

Zhao, Ningning,Strehmel, Bernd,Gorman, Anthony A.,Hamblett, Ian,Neckers, Douglas C.

, p. 7757 - 7765 (1999)

(l-Naphthoyl)diphenylphosphine oxide (1) was synthesized and characterized and its photochemistry investigated using emission spectroscopy, pulse radiolysis, and nanosecond laser flash photolysis. Fluorescence quantum yields are low in aprotic polar and nonpolar solvents. In methanol, as a result of hydrogen-bonding, change of S1 from an n,π* state to a π,π* state leads to the decrease in the rate constant for intersystem crossing and results, finally, in an increase in fluorescence. Preferential solvation was evaluated using the ET indicator "Reichardt's dye" (RD). ETN values were determined by gradually increasing the concentrations of methanol in methanol/acetonitrile mixtures. Fluorescence quantum yields correlate with the ETN values. Photolysis of 1 yields diphenyl[l-naphthoyl)oxy]phosphine (6), formed mainly via cage recombination of radicals. No radicals were detected by either nanosecond laser flash photolysis or pulse radiolysis of 1 in aprotic solvents. However, photolysis in methanol yields radicals when 1 is excited at 266 nm. The phosphinoyl radical can be quenched by either methyl methacrylate (MMA) or oxygen (kq = 5.0 × 107 and 5.3 × 108 M-1 s-1, respectively). Such radical generation most likely results from the singlet excited state.

Electrochemical Oxidative C–H Phosphonylation of thiazole derivatives in ambient conditions

Li, Yang,Wu, Lei,Yang, Yan-Tong,Zhu, Jie,Zhu, Peng-Wei

, (2021/12/07)

We herein report a direct electrochemical dehydrogenative C–H phosphonylation of thiazoles derivatives with H2 evolution. Employing electricity as the green and sole oxidant, cheap metal as electrode, the anodic oxidation together with cathodic hydrogen evolution process provides a green and efficient strategy for C–H phosphonylation. A diverse range of phosphorus products were constructed under external metal and oxidant-free conditions at ambient temperature, featuring atom economy, simple operation and wide reaction scope.

Monoacylphosphine oxides with substituents in the phosphonyl moiety as Norrish I photoinitiators: Synthesis, photoinitiattion properties and mechanism

Duan, Haodong,Gao, Jun,Han, Yuxi,Leng, Kangwei,Li, Qianmin,Liu, Dayong,Wang, Zhongwei,Xu, Xiaolei,Yu, Qing

, (2021/09/07)

In order to study the effect of the substituents in the phosphonyl moiety of monoacylphosphine oxide (MAPO) on its stability and initiation performance, (2,4,6-trimethylphenyl)(phenyl)(benzoyl)phosphine oxide (TMBPO), (4-tolyl)(phenyl)(2,4,6-trimethylbenzoyl)phosphine oxide (4-MTPO) and (2,4-xylyl)(phenyl)(2,4,6-trimethylbenzoyl)phosphine oxide (2,4-DMTPO) were designed and prepared. Studies on TMBPO showed that the introduction of methyl groups into the phosphonyl moiety of MAPO significantly enhanced its stability and light absorption abilities. The photopolymerization of trimethylolpropane triacrylate (TMPTA) showed that the initiation efficiency of 4-MTPO and 2,4-DMTPO were higher than that of TPO, regardless of whether it was initiated upon LED at 385 nm or 420 nm. In addition, the migration rates of 4-MTPO and 2,4-DMTPO in cured TMPTA were approximately 1/2 and 1/4 that of TPO, respectively.
