81316-87-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81316-87-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,3,1 and 6 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 81316-87:
(7*8)+(6*1)+(5*3)+(4*1)+(3*6)+(2*8)+(1*7)=122
122 % 10 = 2
So 81316-87-2 is a valid CAS Registry Number.

Separation and Characterization of Mononitro Derivatives of Benzopyrene, Benzopyrene and Benzoperylene
Johansen, Einar,Sydnes, Leiv K.,Greibrokk, Tyge
, p. 309 - 318 (2007/10/02)
Mononitro derivatives of three polycyclic aromatic hydrocarbons with 5-6 condensed rings have been synthesized and purified to a purity of approximately 99.9 percent for measurements of mutagenic properties.Structural isomers were identified from 1H NMR, MS and UV spectra.
