Check Digit Verification of cas no

The CAS Registry Mumber 1428331-72-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,8,3,3 and 1 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1428331-72:
(9*1)+(8*4)+(7*2)+(6*8)+(5*3)+(4*3)+(3*1)+(2*7)+(1*2)=149
149 % 10 = 9
So 1428331-72-9 is a valid CAS Registry Number.

Iron(II)-catalyzed benzylic fluorination

Bloom, Steven,Pitts, Cody Ross,Woltornist, Ryan,Griswold, Andrew,Holl, Maxwell Gargiulo,Lectka, Thomas

, p. 1722 - 1724 (2013)

Direct C-F functionalization of benzylic sp3 C-H bonds is a synthetic challenge that has yet to be propitiously overcome. A mild, one-pot synthesis of monofluorinated benzylic substrates is reported with commercially available iron(II) acetylacetonate and Selectfluor in good to excellent yields and selectivity. A convenient route to β-fluorinated products of 3-aryl ketones is also highlighted, providing a synthetic equivalent to the difficult to accomplish conjugate addition of fluoride to α,β-unsaturated ketones.
