462-41-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 462-41-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,6 and 2 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 462-41:
(5*4)+(4*6)+(3*2)+(2*4)+(1*1)=59
59 % 10 = 9
So 462-41-9 is a valid CAS Registry Number.

Preparation method of fluorine-containing primary amine intermediate

-

Paragraph 0030; 0032; 0035; 0040, (2021/07/01)

The invention discloses a preparation method of a fluorine-containing primary amine intermediate. The method comprises the following steps: directly fluorinating an N-hydroxyalkyl phthalimide compound serving as a raw material under the action of an organic solvent and a Lewis acid catalyst to obtain an N-fluoroalkyl phthalimide intermediate, and reducing the intermediate to obtain the fluorine-containing primary amine. According to the method, the raw materials are cheap and easy to obtain, the process route is simple and easy to control, the N-hydroxyalkylphthalimide can be effectively promoted to generate the corresponding fluoride at a high conversion rate, meanwhile, the dehydrofluorination reaction in the fluorination process can be avoided, the yield of the fluoride intermediate is 85% or above, the purity reaches 97% or above, and the method is suitable for large-scale production.
