Check Digit Verification of cas no

The CAS Registry Mumber 1420475-73-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,0,4,7 and 5 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1420475-73:
(9*1)+(8*4)+(7*2)+(6*0)+(5*4)+(4*7)+(3*5)+(2*7)+(1*3)=135
135 % 10 = 5
So 1420475-73-5 is a valid CAS Registry Number.

Chemical photocatalysis with 1-(N, N-dimethylamino)pyrene

Penner, Alexander,B?tzner, Effi,Wagenknecht, Hans-Achim

, p. 2803 - 2807 (2012)

1-(N,N-Dimethylamino)pyrene was applied as chemical photocatalyst for two different organic reactions: Both the photocatalytically driven nucleophilic addition of methanol to 1,1-diphenylethylene and the photocatalytic deprotection of N-phenylsulfonylindole gave the corresponding products in good yields and in a highly sustainable way after short irradiation with high-power LED. This concept can potentially be transferred to other photochemical reactions. Copyright
