Check Digit Verification of cas no
The CAS Registry Mumber 101182-89-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,1,1,8 and 2 respectively; the second part has 2 digits, 8 and 9 respectively. Calculate Digit Verification of CAS Registry Number 101182-89: (8*1)+(7*0)+(6*1)+(5*1)+(4*8)+(3*2)+(2*8)+(1*9)=82 82 % 10 = 2 So 101182-89-2 is a valid CAS Registry Number.
Provided is a method for producing a desired perfluorinated product with high yield by a fluorination reaction of a partially fluorinated ester. A compound (3), which is produced by reacting a compound (1) with a compound (2) (and which has a fluorine content of 30 mass% or more), is fluorinated in a liquid phase to produce a perfluorinated compound (4), wherein the compound (1) is represented by the formula HOCH2-RA-CH2OH and the compound (2) is represented by the formula X1C(=O)-C(RB)(RC)(RD). RA represents a bivalent saturated hydrocarbon group or the like and does not have a hetero atom such as an ethereal oxygen atom. X1 represents a halogen atom, and -C(RB)(RC)(RD) represents a branched group.

It is an object to obtain from a mixture of a specific diene compound (1) and a compound (2) with the same molecular weight and molecular formula hard to separate by distillation, the diene compound (1) in high purity without using any special reagent or complicated technique. Namely, the present invention provides a method of inducing the Claisen rearrangement reaction of the compound (2) in a mixture containingCR1R2=CR3CFR4CR5R6OCR7=CR8R9 andCFR1R2CR3=CR4CR5R6OCR7=CR8R9 and separating the diene compound (1) from a Claisen rearrangement reaction product; or converting the Claisen rearrangement reaction product into a derivative and then separating the diene compound (1) from the derivative of the Claisen rearrangement reaction product. Wherein, R1 to R9 each represent a fluorine atom or the like.
