Calculate Digit Verification of CAS Registry Number 1402597-06:
(9*1)+(8*4)+(7*0)+(6*2)+(5*5)+(4*9)+(3*7)+(2*0)+(1*6)=141
141 % 10 = 1

A convenient method for the preparation of mono- and bis-substituted photochromic bis(benzothienyl)perfluorocyclopentenes via regioselective Friedel-Crafts acylation

Bogacheva, A. M.,Charushin, V. N.,Yarovenko, V. N.,Struchkova, M. I.,Krayushkin, M. M.,Levchenko, K. S.,Shmelin, P. S.,Kobeleva, O. I.,Valova, T. M.,Barachevsky, V. A.

The regioselective Friedel-Crafts acylation of 1,2-bis(2-methylbenzo[b] thien-3-yl)hexafluorocyclopentene was developed. Depending on the reaction conditions, mono- or bis(bromoacetyl) derivatives are formed as single products in good yields. Further heterocyclizations involving α-bromoketone moieties gave a series of new photochromic compounds.
