57248-95-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 57248-95-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,2,4 and 8 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 57248-95:
(7*5)+(6*7)+(5*2)+(4*4)+(3*8)+(2*9)+(1*5)=150
150 % 10 = 0
So 57248-95-0 is a valid CAS Registry Number.

SYNTHESIS AND PHOTOCHEMICAL CHARACTERISTICS OF THE PHENOXY DERIVATIVES OF BENZANTHRONE
Gerasimenko, Yu. E.,Sokolyuk, N. T.,Pisulina, L. P.
, p. 566 - 570 (2007/10/02)
The synthesis of 6,8- 6,11-, and 8,11-diphenoxybenzanthrones was realized.It was shown that their benzene solutions (unlike those of their heterocyclic ?-electronic analogs phenoxyanthra- and naphthacenopyridines) are nonphotochromic.
