Check Digit Verification of cas no

The CAS Registry Mumber 252204-14-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,2,2,0 and 4 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 252204-14:
(8*2)+(7*5)+(6*2)+(5*2)+(4*0)+(3*4)+(2*1)+(1*4)=91
91 % 10 = 1
So 252204-14-1 is a valid CAS Registry Number.

Synthesis of CC-1065 and duocarmycin analogs via intramolecular aryl radical cyclization of a tethered vinyl chloride

Boger, Dale L.,Boyce, Christopher W.,Garbaccio, Robert M.,Searcey, Mark

, p. 2227 - 2230 (1998)

The 5-exo-trig radical cyclization of an aryl halide onto a tethered vinyl chloride produces the 3-chloromethyl dihydroindole precursors for CC- 1065 and duocarmycin analogs with chlorine installed as a suitable leaving group for subsequent cyclopropane spirocyclization. The generality of this approach was examined in the context of six CC-1065 and duocarmycin analogs previously synthesized in this laboratory.
