679-03-8 Usage
General Description
4,4,5,5,6,6,6-Heptafluorohex-2-en-1-ol is a fluorinated alcohol compound with the molecular formula C6H2F7O. It is a colorless liquid with a strong characteristic odor, and is often used as a building block in the synthesis of various pharmaceuticals, agrochemicals and specialty chemicals. It is highly reactive due to the presence of the double bond in its structure, and is used as a key intermediate for the production of fluorochemicals and fluoropolymers. Additionally, it has applications in the production of insecticides, herbicides and other agricultural chemicals. However, it is considered to be hazardous, as it is a strong irritant to the skin, eyes and respiratory tract, and should be handled and used with caution.
Check Digit Verification of cas no
The CAS Registry Mumber 679-03-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,7 and 9 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 679-03:
(5*6)+(4*7)+(3*9)+(2*0)+(1*3)=88
88 % 10 = 8
So 679-03-8 is a valid CAS Registry Number.

Ultrasound-Promoted Selective Perfluoroalkylation on the Desired Position of Organic Molecules
Kitazume, Tomoya,Ishikawa, Nobuo

Perfluoroalkylzinc iodides or bromides wich were prepared from perfluoroalkyl iodides or bromides and zinc powder in N,N-dimethylformamide or tetrahydrofuran with ultrasonic irradiation were found to behave as potential perfluoroalkylating reagents for the preparation of a wide variety of perfluoroalkylated compounds.Especially, the ultrasound-promoted asymmetric induction with perfluoroalkyl group on the asymmetrical carbon was achieved by the reaction of perfluoroalkyl halides with optically active enamines in the presence of zinc powder and a catalytic amount of dichlorobis(?-cyclopentadienyl)titanium.
