Check Digit Verification of cas no
The CAS Registry Mumber 135733-71-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,7,3 and 3 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 135733-71:
(8*1)+(7*3)+(6*5)+(5*7)+(4*3)+(3*3)+(2*7)+(1*1)=130
130 % 10 = 0
So 135733-71-0 is a valid CAS Registry Number.

A General Procedure for the Fluorodenitration of Aromatic Substrates

The synthesis of several fluoroaromatic compounds by a new procedure of fluorodenitration of nitroarenes is reported.The methodology is based on the principle that the nitrite ion, generated during the fluorodenitration processes and responsible for most of the undesired side reactions, can be trapped with a suitable reagent, e.g., phthaloyl difluoride or tetrafluorophthaloyl difluoride.The yields of fluoro compounds thus obtained are good to excellent, and the procedure is of general application.
