Check Digit Verification of cas no

The CAS Registry Mumber 40599-19-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,5,9 and 9 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 40599-19:
(7*4)+(6*0)+(5*5)+(4*9)+(3*9)+(2*1)+(1*9)=127
127 % 10 = 7
So 40599-19-7 is a valid CAS Registry Number.

Cobaloxime-Catalyzed Hydroperfluoroalkylation of Electron-Deficient Alkenes with Perfluoroalkyl Halides: Reaction and Mechanism

Hu, Chan-Ming,Qiu, Yao-Ling

, p. 3339 - 3342 (2007/10/02)

Direct hydroperfluoralkylation of electron-deficient alkenes - ethyl acrylates 4, 7, and 8, acrylonitrile (5), and methyl vinyl ketone (6) - with perfluoroalkyl halides RfX (1, X = I; 2, X = Br) in the presence of cobaloxime(III) (3) and zinc gives 1:1 hydroperfluoroalkylation adducts in good yields.This reaction provides a convenient synthesis of β-(perfluoroalkyl)carboxylic esters 9, 12, and 13, nitriles 10, and ketones 11.Details of the reaction including effect of solvent, temperature, and ratio of reagents were examined.The reaction is proposed to proceed via a radical mechanism initiated by low-valent cobalt.
