Check Digit Verification of cas no

The CAS Registry Mumber 193023-27-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,3,0,2 and 3 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 193023-27:
(8*1)+(7*9)+(6*3)+(5*0)+(4*2)+(3*3)+(2*2)+(1*7)=117
117 % 10 = 7
So 193023-27-7 is a valid CAS Registry Number.

Opening of cyclopropyl ketones with SmI2 . Synthesis of spirocyclic and bicyclic ketones by intramolecular trapping of an electrophile

Molander, Gary A.,Alonso-Alija, Cristina

, p. 8067 - 8084 (2007/10/03)

A method for the opening of cyclopropyl ketones with samarium (II) iodide followed by the intramolecular trapping of an electrophile is described. This process leads to the obtainment of functionalized spirocyclic, bicyclic, and tricyclic ketones in moderate to good yields.
