Check Digit Verification of cas no

The CAS Registry Mumber 201813-54-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,1,8,1 and 3 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 201813-54:
(8*2)+(7*0)+(6*1)+(5*8)+(4*1)+(3*3)+(2*5)+(1*4)=89
89 % 10 = 9
So 201813-54-9 is a valid CAS Registry Number.

Heck reaction of arenediazonium salts with N,N-diprotected allylamines. Synthesis of cinnamylamines and indoles

Cacchi, Sandro,Fabrizi, Giancarlo,Goggiamani, Antonella,Sferrazza, Alessio

supporting information; experimental part, p. 1727 - 1730 (2011/05/03)

Novel palladium-catalyzed reactions of arenediazonium tetrafluoroborates with N,N-diprotected allylamines are presented. The reaction of arenediazonium tetrafluoroborates with N,N-(Boc)2 allylamine allows for an easy approach to cinnamylamines whereas using 2-alkynyl-N-(allyl) trifluoroacetanilides and 2-iodo-N-(allyl)trifluoroacetanilide the reaction provides a useful tool for appending indole rings to aniline fragments.
