Check Digit Verification of cas no

The CAS Registry Mumber 75184-22-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,1,8 and 4 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 75184-22:
(7*7)+(6*5)+(5*1)+(4*8)+(3*4)+(2*2)+(1*2)=134
134 % 10 = 4
So 75184-22-4 is a valid CAS Registry Number.

Synthesis of Bicyclic Non-conjugated Polyenes. Stereochemistry and Transanular Interactions

Martin, Hans-Dieter,Heller, Constanze,Mayer, Bernhard,Beckhaus, Hans-Dieter

, p. 2589 - 2600 (2007/10/02)

The synthesis of the bicyclic polyenes 8 - 11 has been achieved by cleavage of the strained ?-bonds of suitable cyclopropanedimethanols 14b/15b and cyclobutanedimethanol-bis(methanesulfonates) 16c/17c using P2I4 (14b/15b) or Zn/KBr (16c/17c), respectively.From an inspection of the 1H NMR spectra a preferred endo-conformation (chair) for 8 and a twisted structure (twist-chair) for 10 is proposed.The predicted extent of transanular conjugation for these geometries is in accordance with the photoelectron spectroscopic measurements.
