Check Digit Verification of cas no
The CAS Registry Mumber 139694-97-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,6,9 and 4 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 139694-97:
(8*1)+(7*3)+(6*9)+(5*6)+(4*9)+(3*4)+(2*9)+(1*7)=186
186 % 10 = 6
So 139694-97-6 is a valid CAS Registry Number.

A SIMPLE APPROACH TO HOMOTROPANES AND HOMOTROP-7-ENES
Malpass, John R.,Smith, Craig
, p. 273 - 276 (1992)
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
