Check Digit Verification of cas no

The CAS Registry Mumber 705297-48-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,0,5,2,9 and 7 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 705297-48:
(8*7)+(7*0)+(6*5)+(5*2)+(4*9)+(3*7)+(2*4)+(1*8)=169
169 % 10 = 9
So 705297-48-9 is a valid CAS Registry Number.

Radical and palladium-catalyzed cyclizations to cyclobutenes: An entry to the BCD ring system of penitrem D

Rivkin, Alexey,Gonzalez-Lopez De Turiso, Felix,Nagashima, Tadamichi,Curran, Dennis P.

, p. 3719 - 3725 (2007/10/03)

A novel approach toward the synthesis of the BCD ring system of penitrem D is described. The strategy capitalizes on the fast cyclization rates of aryl radicals into cyclobutenes and allows access to a variety of fused tricyclic structures. Radical/polar
