284-18-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 284-18-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,8 and 4 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 284-18:
(5*2)+(4*8)+(3*4)+(2*1)+(1*8)=64
64 % 10 = 4
So 284-18-4 is a valid CAS Registry Number.

A SIMPLE APPROACH TO HOMOTROPANES AND HOMOTROP-7-ENES
Malpass, John R.,Smith, Craig
, p. 273 - 276 (2007/10/02)
1,4-Functionalisation of cycloocta-1,3-diene using a nitroso-cycloaddition strategy is followed by intramolecular cyclisation to yield 9-azabicyclononanes (homotropanes) and -non-7-enes (homotrop-7-enes); the approach can be adapted to allow access
