Check Digit Verification of cas no

The CAS Registry Mumber 137678-97-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,6,7 and 8 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 137678-97:
(8*1)+(7*3)+(6*7)+(5*6)+(4*7)+(3*8)+(2*9)+(1*7)=178
178 % 10 = 8
So 137678-97-8 is a valid CAS Registry Number.

Some novel electron transfer mediated cascade ring-opening reactions of bicyclo[4.1.0]ketones

Batey, Robert A.,Harling, John D.,Motherwell, William B.

, p. 11421 - 11444 (1996)

The radical ring-opening reactions of cyclopropyl ketones, mediated by samarium (II) iodide and other electron transfer agents are described. This strategy allows tandem rearrangement cyclisation reactions and the trapping of the resultant samarium (III) enolates by a variety of electrophiles, for the construction of complex bicyclic systems.
