The CAS Registry Mumber 1220184-63-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,0,1,8 and 4 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1220184-63:
(9*1)+(8*2)+(7*2)+(6*0)+(5*1)+(4*8)+(3*4)+(2*6)+(1*3)=103
103 % 10 = 3

A new method for halogenation of aromatic compounds by using dimethyldioxirane and tetrabutylammonium halides

Lee, Yean-Jang,Wu, Huan-Ting,Lin, Chia-Ning

, p. 585 - 587 (2009)

In this presentation the novel regioselective halogenation of arenes or phenols with dimethyldioxirane and Bu4NX is described. The results showed that a new, versatile and mild method can be utilized for preparation of aryl halides starting with arenes or phenols. Finally, this aryl halide forming methodology is applicable to structurally more complex flavonoids.
