1407803-87-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1407803-87-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,7,8,0 and 3 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1407803-87:
(9*1)+(8*4)+(7*0)+(6*7)+(5*8)+(4*0)+(3*3)+(2*8)+(1*7)=155
155 % 10 = 5
So 1407803-87-5 is a valid CAS Registry Number.

Total synthesis of chlorocyclinone A, a PPAR-γ antagonist
Karmakar, Raju,Mal, Dipakranjan
, p. 10235 - 10248 (2013/01/15)
The first total synthesis of chlorocyclinone A (1) is regioselectively completed in 28 steps. The key steps are Pd-catalyzed methoxycarbonylation, unprecedented Hauser annulation, Krohn photo-oxidation, and regioselective gem-dichlorination.
