115120-98-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 115120-98-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,5,1,2 and 0 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 115120-98:
(8*1)+(7*1)+(6*5)+(5*1)+(4*2)+(3*0)+(2*9)+(1*8)=84
84 % 10 = 4
So 115120-98-4 is a valid CAS Registry Number.

, 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
