Check Digit Verification of cas no

The CAS Registry Mumber 64414-43-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,4,1 and 4 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 64414-43:
(7*6)+(6*4)+(5*4)+(4*1)+(3*4)+(2*4)+(1*3)=113
113 % 10 = 3
So 64414-43-3 is a valid CAS Registry Number.

13C-1H Coupling Constants in Carbocations. 6. Generation and Trapping of the (1aα,7aα)-1a,2,7,7a-Tetrahydro-1H-cyclopropanaphthalene-2-yl Cation

Kelly, David P.,Banwell, Martin G.,Ireland, Neil K.,Noel, Allison L.

, p. 2040 - 2045 (2007/10/02)

New synthetic routes to (1aα,2β,7bα)-1a,2,3,7b-tetrahydro-1H-cyclopropanaphthalen-2-ol (4b) and (1aα,2α,7aα)-1a,2,7,7a-tetrahydro-1H-cyclopropanaphthalene-2-ol (6b) have been established involving dichlorocarbene addition to the appropriate dihydronaphthalene as the key step.Ionization of either alcohol 4b or 6b in FSO3H/SO2ClF at -130 deg C produces the title cation 5b, in which the positive charge is stabilized by the adjacent benzo and cyclopropyl moieties.This is the same cation as that obtained previously by protonation of 1,6-methanoannulene (1).Generation of the cation 5b by protonation of C11-13C-enriched 1 has shown that the C11 bridge methylene carbon is incorporated into both benzylic positions (C2 ad C7) and not the apical cyclopropyl carbon (C1).Application of the ΔJ equation shows that 5b adopts an anti-boat conformation in this superacid medium.
