1286201-53-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1286201-53-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,6,2,0 and 1 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1286201-53:
(9*1)+(8*2)+(7*8)+(6*6)+(5*2)+(4*0)+(3*1)+(2*5)+(1*3)=143
143 % 10 = 3
So 1286201-53-3 is a valid CAS Registry Number.

Galer, Petra,Ko?mrlj, Berta,?ket, Boris
, p. 2103 - 2109 (2011/04/22)
Halogenation of 1-phenyl-3-(3,5-dimethoxyphenyl)-propane-1,3-dione (1) with N-X reagents take place regioselectively at the α position (except for fluorination), while halogenation of its BF2 derivative 3 take place regioselectively at position
