Check Digit Verification of cas no

The CAS Registry Mumber 83411-71-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,4,1 and 1 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 83411-71:
(7*8)+(6*3)+(5*4)+(4*1)+(3*1)+(2*7)+(1*1)=116
116 % 10 = 6
So 83411-71-6 is a valid CAS Registry Number.

Method for preparing dialkyl phosphinic acid or salt thereof

-

Paragraph 0117-0125, (2021/04/17)

The invention discloses a method for preparing dialkyl phosphinic acid or salt thereof. The method is a method I or a method II. The method I comprises the following steps: in a solvent, in the presence of a free radical initiator and a catalyst, carrying out free radical addition reaction on phosphinic acid and olefin as shown in a formula (II) to prepare dialkyl phosphinic acid. The method II comprises the step: in a solvent, in the presence of a free radical initiator and a catalyst, carrying out free radical addition reaction on a compound shown in the formula (I) and olefin shown in the formula (II) to obtain dialkyl phosphinate. According to the method, high-purity and high-yield preparation of dialkyl phosphinic acid or salt thereof is achieved by adding the catalyst, subsequent complex purification work is avoided, the reaction time is remarkably shortened, and compared with the prior art, the method has the advantages of being simple, low in cost and high in purity.

Microwave-assisted synthesis of dialkylphosphinic acids and a structure-reactivity study in rare earth metal extraction

Du, Ruo-Bing,An, Huaying,Zhang, Suhui,Yu, Donghai,Xiao, Ji-Chang

, p. 104258 - 104262 (2015/12/24)

Dialkylphosphinic acids were synthesised by a microwave-assisted method with high yields and wide substrate applicability. A structure-reactivity study indicates that an increase in steric hindrance in the β position led to a decrease of extraction ratio and heavy rare earth element separation activity. A computational study was also conducted to understand the steric effect.

NOVEL PHOSPHINIC ACIDS AND THEIR SULFUR DERIVATIVES AND METHODS FOR THEIR PREPARATION

-

Page/Page column 25-28, (2008/06/13)

The present invention provides phosphinic acids and their sulfur derivatives, in accordance with the following formula (I): wherein R1 and R2 are different and each of R1 and R2 is independently selected from an organic radical that branches at the alpha carbon and an organic radical that branches at the beta carbon, and each of X and Y is independently O or S, and wherein said compound is a liquid at room temperature. Compounds of formula (I) find utility for example as metal extractants. Also provided are methods for making compounds of formula (I) and their corresponding phosphine intermediates.
