Check Digit Verification of cas no
The CAS Registry Mumber 2058-94-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,0,5 and 8 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 2058-94:
(6*2)+(5*0)+(4*5)+(3*8)+(2*9)+(1*4)=78
78 % 10 = 8
So 2058-94-8 is a valid CAS Registry Number.

A NEW METHOD FOR THE PREPARATION OF PERFLUOROCARBOXYLIC ACIDS
Huang, Bing-Nan,Haas, A.,Lieb, M.
, p. 49 - 62 (2007/10/02)
The reaction of both primary perfluoroalkyl iodides and bromides containing 3-12 carbon atoms with a rongalite-NaHCO3 reagent in aqueous dipolar aprotic solvents, such as DMF or DMSO, has been investigated.The reaction gave sodium perfluorocarboxylates in 51-86percent yields, and these were transformed to the respective perfluorocarboxylic acids by treatment with sulfuric acid.This provides a new method for the synthesis of perfluorocarboxylic acids.
