Check Digit Verification of cas no

The CAS Registry Mumber 131559-11-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,5,5 and 9 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 131559-11:
(8*1)+(7*3)+(6*1)+(5*5)+(4*5)+(3*9)+(2*1)+(1*1)=110
110 % 10 = 0
So 131559-11-0 is a valid CAS Registry Number.

PHOTOLYSIS OF 1,2-ANTHRAQUINONE DIAZIDE IN AROMATIC HYDROCARBONS

Klimenko, L. S.,Mainagashev, J Ya.,Fokin, E. P.

, p. 789 - 791 (1992)

It has been determined that the main products of photolysis of 1,2-anthraquinone diazide in benzene, toluene, anisole, nitrobenzene, and pyridine are the corresponding 1-hydroxy-2-arylanthraquinones that forms as a mixture of ortho, meta, and para isomers with significant content of the meta isomer (40-55percent). Keywords: photolysis, 1,2-anthraquinone diazide, aromatic hydrocarbons, isomers.
