Check Digit Verification of cas no
The CAS Registry Mumber 41405-35-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,1,4,0 and 5 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 41405-35:
(7*4)+(6*1)+(5*4)+(4*0)+(3*5)+(2*3)+(1*5)=80
80 % 10 = 0
So 41405-35-0 is a valid CAS Registry Number.

Preparation method of perfluoroheptanoic acid
-
, (2017/07/22)
The invention relates to the technical field of fluorochemical preparation, particularly a preparation method of perfluoroheptanoic acid. The method comprises the following steps: oxidizing dodecafluoroheptanol to obtain dodecafluoroheptanoic acid, carrying out reaction on the dodecafluoroheptanoic acid and thionyl chloride to obtain dodecafluoroheptanoyl chloride, carrying out fluorination on the dodecafluoroheptanoyl chloride to obtain perfluoroheptanoyl chloride, and hydrolyzing to obtain the perfluoroheptanoic acid. The technical process of preparing perfluoroheptanoic acid from dodecafluoroheptanol has the advantages of low energy consumption, no pollution and high yield (up to 75% or above), is easy to operate, and has higher competitive edges than the existing perfluoroheptanoic acid production technique.
