920515-67-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 920515-67-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,0,5,1 and 5 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 920515-67:
(8*9)+(7*2)+(6*0)+(5*5)+(4*1)+(3*5)+(2*6)+(1*7)=149
149 % 10 = 9
So 920515-67-9 is a valid CAS Registry Number.

Palladium-catalyzed alkylation-alkenylation reactions: Rapid access to tricyclic mescaline analogues
Alberico, Dino,Lautens, Mark
, p. 2969 - 2972 (2006)
A norbornene-mediated palladium-catalyzed sequence is described in which two alkyl-aryl bonds and one alkenyl-aryl bond are formed in one pot. A variety of symmetrical and unsymmetrical tricyclic heterocycles were synthesized in good yields from a Heck ac
