59856-29-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 59856-29-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,9,8,5 and 6 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 59856-29:
(7*5)+(6*9)+(5*8)+(4*5)+(3*6)+(2*2)+(1*9)=180
180 % 10 = 0
So 59856-29-0 is a valid CAS Registry Number.

Nucleophilic Chlorination of 3-Formyl-4-hydroxy-quinolin-2(1H)-ones
Fiala, Werner,Stadlbauer, Wolfgang
, p. 128 - 134 (2007/10/02)
Chlorination of 1-substituted 3-formyl-4-hydroxy-2-quinolones (1a, b) with phosphorylchloride leads to 4-chloro-3-dichloromethylquinolones (2), which can be hydrolyzed to 4-chloro-3-formylquinolones (4).From the anilinomethylene quinolinediones (3), at lo
