Check Digit Verification of cas no
The CAS Registry Mumber 146960-90-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,6,9,6 and 0 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 146960-90:
(8*1)+(7*4)+(6*6)+(5*9)+(4*6)+(3*0)+(2*9)+(1*0)=159
159 % 10 = 9
So 146960-90-9 is a valid CAS Registry Number.

A ferrocene diphosphine ligand preparation method
-
Paragraph 0006; 0021; 0022, (2017/08/31)
The invention discloses a method for preparing ferrocene diphosphine ligand, and belongs to the field of organic synthesis. The method comprises the following steps: by taking ferrocene as an initial raw material and boron trifluoride diethyl etherate as a catalyst, reacting with diaryl phosphine oxide or dialkyl phosphine oxide, hydrolyzing so as to obtain tertfluoborate of a ferrocene diphosphine compound, and performing heating backflow deprotection in methanol, thereby obtaining the ferrocene diphosphine compound. Compared with the prior art, the method is gentle in reaction condition, simple in aftertreatment, and relatively applicable to industrial production, and the yield is greater than 90%. The prepared ferrocene diphosphine can be used as ligand of a metal catalyst, and can be used in the fields such as organic optoelectronic materials and medicines.
