Check Digit Verification of cas no
The CAS Registry Mumber 87351-03-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,3,5 and 1 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 87351-03:
(7*8)+(6*7)+(5*3)+(4*5)+(3*1)+(2*0)+(1*3)=139
139 % 10 = 9
So 87351-03-9 is a valid CAS Registry Number.

Palladium-Catalyzed Conjugate Addition Type Reaction of Aryl Iodides with α,β-Unsaturated Ketones
Cacchi, S.,Arcadi, A.
, p. 4236 - 4240 (2007/10/02)
Aryl iodides have been found to react with α,β-unsaturated ketones in the presence of catalytic amounts of palladium, an excess of formic acid, and triethylamine, giving rise to conjugate addition type products.The electron-withdrawing power of the group attached to the olefinic double bond, the substituent β to the carbonyl group, and the basic reaction medium appear to effect greatly the conjugate addition/vinylic substitution ratio.
