20928-82-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 20928-82-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,9,2 and 8 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 20928-82:
(7*2)+(6*0)+(5*9)+(4*2)+(3*8)+(2*8)+(1*2)=109
109 % 10 = 9
So 20928-82-9 is a valid CAS Registry Number.

Photochemical generation of nitric oxide from 6-nitrobenzo[a]pyrene
Fukuhara,Kurihara,Miyata
, p. 8662 - 8666 (2007/10/03)
Photolabile 6-nitrobenzo[a]pyrene (6-nitroBaP) released nitric oxide (NO) under visible-light irradiation. The generation of NO and the concomitant formation of the 6-oxyBaP radical were confirmed by ESR. BaP quinones were also detected as further oxidize
