Check Digit Verification of cas no

The CAS Registry Mumber 1239896-66-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,9,8,9 and 6 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1239896-66:
(9*1)+(8*2)+(7*3)+(6*9)+(5*8)+(4*9)+(3*6)+(2*6)+(1*6)=212
212 % 10 = 2
So 1239896-66-2 is a valid CAS Registry Number.

Palladium-catalyzed synthesis of 4-arylcoumarins using triarylbismuth compounds as atom-Efficient multicoupling organometallic nucleophiles

Rao, Maddali L. N.,Venkatesh, Varadhachari,Jadhav, Deepak N.

experimental part, p. 3945 - 3955 (2010/09/05)

Triarylbismuth compounds have been cross-coupled as atomefficient multicoupling organometallic nucleophiles with. 4bromo- and 4- (trifluoromethylsulfonyloxy)coumarins under palladium catalysis conditions. These reactions afforded an array of 4-arylcoumari
