Check Digit Verification of cas no

The CAS Registry Mumber 352-91-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,5 and 2 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 352-91:
(5*3)+(4*5)+(3*2)+(2*9)+(1*1)=60
60 % 10 = 0
So 352-91-0 is a valid CAS Registry Number.

A Rapid and Efficient Method for the Fluoroalkylation of Amines and Amides. Development of a Method Suitable for Incorporation of the Short-Lived Positron Emitting Radionuclide Fluorine-18

, p. 658 - 664 (2007/10/02)

We have described a two-step method for the preparation of fluoroalkyl-substituted amines and amides.The sequence involves fluoride ion displacement of a haloalkyl trifluoromethanesulfonate (triflate), followed by fluoroalkylation of the heteroatom system (amine or amide) by the fluoroalkyl halide.Alternatively, the fluoroalkyl halide can be prepared by halofluorination of a terminal olefin.These reactions have been used to prepare various fluoroalkyl derivatives of N-phenylpiperazine and N-fluoroalkyl derivatives of the neuroleptic agent spiperone (7).The sequence is rapid, convenient, and efficient, even when fluoride ion is the limiting reagent.Therefore, it is readily adaptable to the preparation of a variety of compounds labeled with the short half-life (t1/2 = 110 min) positron-emitting radionuclide fluorine-18.
