116476-55-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 116476-55-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,4,7 and 6 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 116476-55:
(8*1)+(7*1)+(6*6)+(5*4)+(4*7)+(3*6)+(2*5)+(1*5)=132
132 % 10 = 2
So 116476-55-2 is a valid CAS Registry Number.

Malondianilides 3 derived from dichloro substituted anilines 2 undergo cyclization to afford 4-hydroxy-2(1H)-quinolones 4 in very good yields using methane sulfonic acid-phosphorus pentoxide as catalyst. 3,4-Dichloro anilines 5 can be shown to yield two i
