139682-17-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139682-17-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,6,8 and 2 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 139682-17:
(8*1)+(7*3)+(6*9)+(5*6)+(4*8)+(3*2)+(2*1)+(1*7)=160
160 % 10 = 0
So 139682-17-0 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
