134454-81-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134454-81-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,4,5 and 4 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 134454-81:
(8*1)+(7*3)+(6*4)+(5*4)+(4*5)+(3*4)+(2*8)+(1*1)=122
122 % 10 = 2
So 134454-81-2 is a valid CAS Registry Number.

A novel and versatile synthesis of 1-arylbenzocyclobutenols and 1-arylbenzocyclobutenes
Aidhen, Indrapal Singh,Narasimhan, N. S.
, p. 234 - 238 (2007/10/02)
Lithium halogen exchange has been achieved in the substrate 5, in the presence of a carbonyl group, using n-butyllithium.This leads to the first convenient synthesis of 1-arylbenzocyclobutenols (1) in good yields.
