Check Digit Verification of cas no

The CAS Registry Mumber 53250-55-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,2,5 and 0 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 53250-55:
(7*5)+(6*3)+(5*2)+(4*5)+(3*0)+(2*5)+(1*5)=98
98 % 10 = 8
So 53250-55-8 is a valid CAS Registry Number.

Ruthenium-Catalyzed Monoalkenylation of Aromatic Ketones by Cleavage of Carbon-Heteroatom Bonds with Unconventional Chemoselectivity

Kondo, Hikaru,Akiba, Nana,Kochi, Takuya,Kakiuchi, Fumitoshi

supporting information, p. 9293 - 9297 (2015/08/06)

Ruthenium-catalyzed selective monoalkenylation of ortho C-O or C-N bonds of aromatic ketones was achieved. The reaction allowed the direct comparison of the relative reactivities of the cleavage of different carbon-heteroatom bonds, thus suggesting an unc
