Check Digit Verification of cas no
The CAS Registry Mumber 133342-43-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,3,4 and 2 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 133342-43:
(8*1)+(7*3)+(6*3)+(5*3)+(4*4)+(3*2)+(2*4)+(1*3)=95
95 % 10 = 5
So 133342-43-5 is a valid CAS Registry Number.

Phenol compound ortho-position direct fluorination method
-
Paragraph 0046-0048, (2020/04/17)
The invention relates to a phenol compound ortho-position direct fluorination method which comprises the following steps: reacting a phenol compound shown in a formula (1A) with a fluorination reagentin a solvent under the action of a photocatalyst and a light source at room temperature, and separating and purifying a reaction mixture after the reaction to obtain a fluorinated phenol compound shown in a formula (2A). The advantages are as follows: the method for directly fluorinating phenol by organic photocatalysis is simple in operation process; raw materials are commercialized and easy toobtain; the photocatalyst is low in price, easy to obtain and environmentally friendly; the reaction condition is mild; the site selectivity is high; the reaction is efficient; and a fluorinated phenol derivative can be prepared only through one step.
