5350-25-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 5350-25-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,3,5 and 0 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 5350-25:
(6*5)+(5*3)+(4*5)+(3*0)+(2*2)+(1*5)=74
74 % 10 = 4
So 5350-25-4 is a valid CAS Registry Number.

, p. 1450 - 1460 (2007/10/03)
The results of bromination and nitration of Fluorescein were refined, and some mutual transformations and reactions of its bromonitro derivatives were studied. The reaction of 4,5-dinitrofluorescein with aliphatic amines leads to transformation of the xan
