Check Digit Verification of cas no

The CAS Registry Mumber 445007-02-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,5,0,0 and 7 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 445007-02:
(8*4)+(7*4)+(6*5)+(5*0)+(4*0)+(3*7)+(2*0)+(1*2)=113
113 % 10 = 3
So 445007-02-3 is a valid CAS Registry Number.

Carbopalladation of nitriles: Synthesis of benzocyclic ketones and cyclopentenones via Pd-catalyzed cyclization of ω-(2-iodoaryl)alkanenitriles and related compounds

Pletnev, Alexandre A.,Larock, Richard C.

, p. 9428 - 9438 (2007/10/03)

An efficient procedure for the synthesis of 2,2-disubstituted benzocyclic ketones by intramolecular carbopalladation of nitriles has been developed. The cyclization of substituted 3-(2-iodoaryl)-propanenitriles affords indanones in high yields. The reaction is compatible with a wide variety of functional groups. This methodology has been extended to the synthesis of tetralones and cyclopentenones.
