Check Digit Verification of cas no

The CAS Registry Mumber 22187-09-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,1,8 and 7 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 22187-09:
(7*2)+(6*2)+(5*1)+(4*8)+(3*7)+(2*0)+(1*9)=93
93 % 10 = 3
So 22187-09-3 is a valid CAS Registry Number.

Relative Reactivities of Some Polycyclic Aromatic Hydrocarbons in Catalytic Hydrogenation over Raney Nickel

Minabe, Masahiro,Urushibara, Shuuichi,Mishina, Fumihiko,Kimura, Takao,Tsubota, Motohiro

, p. 670 - 672 (2007/10/02)

Catalytic hydrogenation of 9H-fluorene (10), phenanthrene (2), 4H-cyclopentaphenanthrene (3), pyrene (4), and fluoranthene (5) was carried out over Raney nickel (W-7) at 323 K under 608 kPa of hydrogen.The order of the reaction rate was 5>4>3>2>1.The adsorption equilibrium constant of the substrates decreased in the order 4 > or = 5 >> 2 > 3 >> 1.
