165275-20-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 165275-20-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,5,2,7 and 5 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 165275-20:
(8*1)+(7*6)+(6*5)+(5*2)+(4*7)+(3*5)+(2*2)+(1*0)=137
137 % 10 = 7
So 165275-20-7 is a valid CAS Registry Number.

New Homogeneous Rhenium-based Metathesis Catalysts as Models of the Rhenium on Alumina Heterogeneous Catalyst
Commereuc, Dominique
, p. 791 - 792 (1995)
Bis(2,6-di-tert-butyl-4-methylphenoxy)isobutylaluminium reacts with dirhenium heptoxide to give complexes containing aluminium coordinated with perrhenate and 2,6-di-tert-butyl-4-methylphenoxy ligands which are active new catalysts for the metathesis of alkenes.
