339155-42-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 339155-42-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,9,1,5 and 5 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 339155-42:
(8*3)+(7*3)+(6*9)+(5*1)+(4*5)+(3*5)+(2*4)+(1*2)=149
149 % 10 = 9
So 339155-42-9 is a valid CAS Registry Number.

Synthesis and electrophilic substitution of pyrido[2,3,4-kl]-acridines
Koller, Avi,Rudi, Amira,Garcia Gravalos, Marta,Kashman, Yoel
, p. 300 - 322 (2007/10/03)
Several new pyrido[2,3,4-kl]acridines were synthesized by reacting naphthoquinone, juglone or cyclohexan-1,3-dione with β,β'- diaminoketones in a biomimetic reaction. The structure of all new compounds was elucidated by NMR and MS spectroscopy. Electrophi
