Check Digit Verification of cas no

The CAS Registry Mumber 21223-05-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,2,2 and 3 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 21223-05:
(7*2)+(6*1)+(5*2)+(4*2)+(3*3)+(2*0)+(1*5)=52
52 % 10 = 2
So 21223-05-2 is a valid CAS Registry Number.

Interaction of some methylenediphosphanes with hexafluoroacetone and hexafluorothioacetone dimer

Shevchenko, Igor V.,Mikolenko, Rostislav N.,Lork, Enno,Roeschenthaler, Gerd-Volker

, p. 2377 - 2383 (2001)

The reactions of methylenediphosphanes 1a-c with hexafluoroacetone (HFA) and hexafluorothioacetone dimer (HFTA) gave the respective carbodiphosphoranes 5a, 5b, 6, 15, and 19. The carbodiphosphoranes 6 and 19, with phenyl groups at phosphorus, were able to react further with C=O or C=S functions. Compound 6 added one equivalent of HFA across one of the ylidic P=C bonds to give compound 9, a stable intermediate of the Wittig reaction. The addition of HFTA to 19 gave, unexpectedly, the isomeric compound 21. The molecular structures of 9, 15, and 21 were confirmed by X-ray investigations.

Primary Amination of Ar2P(O)-H with (NH4)2CO3as an Ammonia Source under Simple and Mild Conditions and Its Extension to the Construction of Various P-N or P-O Bonds

Han, Ya-Ping,Tan, Yushi,Yang, Shang-Dong,Zhang, Hong-Yu,Zhang, Yuecheng,Zhao, Jiquan

, (2022/02/10)

A facile and efficient method for the synthesis of primary phosphinamides from Ar2P(O)-H reagents with stable and readily available ammonium carbonate as an ammonia source is disclosed herein for the first time. This ethyl bromoacetate-mediated primary am

Electrochemical Dehydrogenative Phosphorylation of Alcohols for the Synthesis of Organophosphinates

Deng, Lingling,Wang, Yang,Mei, Haibo,Pan, Yi,Han, Jianlin

, p. 949 - 956 (2019/01/14)

An eco-friendly and efficient method for the synthesis of organophosphinates via an electrochemical cross-dehydrogenative-coupling reaction between alcohols and secondary phosphine oxides has been developed. This electrochemical reaction was conducted at

A Monocyclic Phosphorane with Hydrogen in Axial Position: Preparation and Molecular Structure

Roeschenthaler, Gerd-Volker,Bohlen, Rainer,Schomburg, Dietmar

, p. 1593 - 1596 (2007/10/02)

Chlorodiphenylphosphane and triethylammonium perfluoropinacolate yield the monocyclic hydrophosphorane 3.The X-ray structure analysis reveals that hydrogen is bonded in the axial position of a trigonal bipyramide.With dimethyl sulfoxide 3 undergoes a ring
