21280-66-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 21280-66-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,2,8 and 0 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 21280-66:
(7*2)+(6*1)+(5*2)+(4*8)+(3*0)+(2*6)+(1*6)=80
80 % 10 = 0
So 21280-66-0 is a valid CAS Registry Number.

SYNTHESIS OF HETEROARYLQUINOLINES BY THE PHOTOLYSIS OF 2-, 3-, AND 4-IODOQUINOLINES
Ohkura, Kazue,Seki, Koh-ichi,Terashima, Masanao,Kanaoka, Yuichi
, p. 957 - 962 (2007/10/02)
Photoreaction of 2-, 3-, and 4-iodoquinolines with five membered heterocycles (i.e. 1-methylpyrrole, pyrrole, furan and thiophene) afforded the corresponding n-(2-heteroaryl)quinolines (n=2, 3, 4) in appreciable yields.
