Check Digit Verification of cas no

The CAS Registry Mumber 4311-02-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,1 and 1 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 4311-02:
(6*4)+(5*3)+(4*1)+(3*1)+(2*0)+(1*2)=48
48 % 10 = 8
So 4311-02-8 is a valid CAS Registry Number.

An efficient approach to dihydrofuroflavonoids via palladium-catalyzed annulation of 1,3-dienes by 0-iodoacetoxyflavonoids

Rozhkov, Roman V.,Larock, Richard C.

, p. 1854 - 1858 (2004)

The palladium-catalyzed annulation of 1,3-dienes by o-iodoacetoxyflavonoids provides an efficient approach to biologically interesting dihydrofuroflavonoids. This reaction is very general, stereo-and regioselective, and a wide variety of terminal, cyclic and internal 1,3-dienes can be utilized.
