148587-01-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 148587-01-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,8,5,8 and 7 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 148587-01:
(8*1)+(7*4)+(6*8)+(5*5)+(4*8)+(3*7)+(2*0)+(1*1)=163
163 % 10 = 3
So 148587-01-3 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
