120937-44-2 Usage
Uses
Di-tert-butylcyclopentadiene may be used in the preparation of 2,5,4′,6′-tetra-tert-butyl-5′H-spirocyclopentane-1,2′-cyclopenta[b][1,3]diselena-2,4-diene and 1,3,5,7-tetra-tert-butyl-3a,7a-dihydro-3a,7a-epi-selenodicyclopenta[b,e][1,4]diselenine.
General Description
Preparation of di-tert-butylcyclopentadiene by phase-transfer-catalyzed alkylation has been reported. It reacts with excess potassium tert-butoxide in the presence of elemental selenium to yield cyclopentadienes bridged by two or three selenium atoms through one or two diselenoketal functionalities. It reacts with excess potassium tert-butoxide in the presence of elemental sulfur to yield cyclopentadienes bridged by sulfur atoms via one or two dithioketal functionalities.
Check Digit Verification of cas no
The CAS Registry Mumber 120937-44-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,9,3 and 7 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 120937-44:
(8*1)+(7*2)+(6*0)+(5*9)+(4*3)+(3*7)+(2*4)+(1*4)=112
112 % 10 = 2
So 120937-44-2 is a valid CAS Registry Number.
