33025-09-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 33025-09-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,0,2 and 5 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 33025-09:
(7*3)+(6*3)+(5*0)+(4*2)+(3*5)+(2*0)+(1*9)=71
71 % 10 = 1
So 33025-09-1 is a valid CAS Registry Number.

Late-Stage Derivatization of Buflavine by Nickel-Catalyzed Direct Substitution of a Methoxy Group via C-O Bond Activation

Shimazumi, Ryoma,Morita, Kosuke,Yoshida, Tomoki,Yasui, Kosuke,Tobisu, Mamoru

, p. 3037 - 3044 (2021/05/06)

The nickel-catalyzed cross-coupling of methoxyarenes was applied to buflavine, which allows for the selective monosubstitution of one of the two methoxy groups in the molecule, leading to the formation of 2- and 3-substituted isomers. Trimethylsilylmethyl (TMSCH 2), phenyl, and alkynyl groups can be introduced into buflavine using this method. The resulting TMSCH 2analogue of buflavine can also be converted into several other derivatives.

Synthesis and characterization of unique nickel(II) carboxylates and their coordination complexes

Shavina,Singh, Baljit

, p. 416 - 420 (2018/01/12)

Direct anodic dissolution of nickel metal and cathodic reduction of carboxylic acids (RCOOH) in acetonitrile has proved to be a simple and efficient one-step route to synthesize unique polymeric nickel(II) carboxylate complexes, {Ni(OOCR)2}n in H-type glass Pyrex cell. When the oxidation was carried out in the presence of neutral ligands (L) such as 2,2’-bipyridyl or 1,10-phenanthroline, the complexes of type {Ni(OOCR)2.L}n were obtained. Tetrabutylammonium chloride has been used as a supporting electrolyte in order to increase the electrolytic conductivity of the electrochemical system which in turn affects the current efficiency, cell voltage and energy consumption in the electrolytic cell. The complexes have been characterized by vibrational spectra, CHN elemental analysis, solubility and melting points shows a good agreement with the structure. The result also shows that the direct electrochemical synthetic technique has high current efficiency, extra purity and yield.

Preparation method of battery grade nickel acetate

-

Paragraph 0038; 0041; 0042; 0043, (2017/08/29)

The invention relates to a preparation method of battery grade nickel acetate, and aims at providing a preparation method of battery grade nickel acetate, which is simple in production principle and wide in raw material source and facilitates industrial production. The preparation method of the battery grade nickel acetate comprises the following steps: metallic nickel powder and an acid copper chloride solution react, impurity removal and evaporation are carried out, and NiCl2 is obtained; NiCl2 is mixed with a sodium hydroxide solution fully, after filtration, Ni(OH)2 is obtained, nickelous hydroxide is washed and then is acidified by acetic acid, and nickel acetate is generated finally. The nickel acetate prepared by the preparation method is high in purity. The preparation method is applied to the technical field of chemical production.
