Check Digit Verification of cas no

The CAS Registry Mumber 57994-68-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,9,9 and 4 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 57994-68:
(7*5)+(6*7)+(5*9)+(4*9)+(3*4)+(2*6)+(1*8)=190
190 % 10 = 0
So 57994-68-0 is a valid CAS Registry Number.

Radical addition of perfluoroalkyl iodides to alkenes and alkynes initiated by sodium dithionite in an aqueous solution in the presence of a novel fluorosurfactant

Xiao, Zhiwei,Hu, Huawei,Ma, Jiaoli,Chen, Qingyun,Guo, Yong

, p. 939 - 944 (2013/08/23)

A new fluorinated anionic surfactant Cl(CF2) 6O(CF2)2SO3N(C2H 5)4 was prepared and characterized. The application of the fluorosurfactant allowed the fluoroalkylation to occur in the water without adding organic solvent. The addition of perfluoroalkyl iodides with olefins and alkynes under the initiation of Na2S2O4 in water in the presence of the fluorosurfactant gave the corresponding adducts in good to excellent yields. The fluorosurfactant was suitable for a radical addition process. A new surfactant Cl(CF2)6O(CF 2)2SO3N(C2H5) 4 was prepared and its properties were measured. The fluorinated surfactant was applied to the fluoroalkylation of perfluoroalkyl iodides with olefins and alkynes. The reactions gave the corresponding adducts in water and avoided the use of organic solvent. The aqueous solution with the surfactant proved to be an effective medium for a radical process.
