Check Digit Verification of cas no

The CAS Registry Mumber 1206189-69-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,6,1,8 and 9 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1206189-69:
(9*1)+(8*2)+(7*0)+(6*6)+(5*1)+(4*8)+(3*9)+(2*6)+(1*9)=146
146 % 10 = 6
So 1206189-69-6 is a valid CAS Registry Number.

Synthesis of [18F]Fluoroarenes by Nucleophilic Radiofluorination of N-Arylsydnones

Narayanam, Maruthi Kumar,Ma, Gaoyuan,Champagne, Pier Alexandre,Houk, Kendall N.,Murphy, Jennifer M.

supporting information, p. 13006 - 13010 (2017/09/28)

A practical method for radiofluorination of anilines with [18F]fluoride via N-arylsydnone intermediates is described. These precursors are stable, easy to handle and facilitate direct and regioselective 18F-labeling to prepare [

NUCLEOPHILIC FLUORINATION OF AROMATIC COMPOUNDS

-

Page/Page column 12-13; 18, (2010/04/03)

Iodylbenzene derivatives substituted with electron donating as well as electron withdrawing groups on the aromatic ring are used as precursors in aromatic nucleophilic substitution reactions. The iodyl group (IO2) is regiospecifically substituted by nucleophilic fluoride to provide the corresponding fluoroaryl derivatives. No-carrier-added [F-18] fluoride ion derived from anhydrous [F- 18]KF/Kryptofix, [F-18]CsF or a quaternary ammonium fluoride (e.g., Me4NF, Et4NF, n-Bu4NF, (PhCH2)4NF) exclusively substitutes the iodyl moiety in these derivatives and provides high specific activity F- 18 labeled fluoroaryl analogs. Iodyl derivatives of a benzothiazole analog and 6-iodyl-L-dopa derivatives have been synthesized as precursors and have been used in the preparation of no-carrier-added [F-18]fluorobenzothiazole as well as 6-[F-18]fluoro-L-dopa.
