Check Digit Verification of cas no

The CAS Registry Mumber 51644-21-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,6,4 and 4 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 51644-21:
(7*5)+(6*1)+(5*6)+(4*4)+(3*4)+(2*2)+(1*1)=104
104 % 10 = 4
So 51644-21-4 is a valid CAS Registry Number.

Rh-IndOlefOx catalyzed conjugate addition/Heck-type coupling of organoboronics to a lactam or a lactone

Kuuloja, Noora,Vaismaa, Matti,Franzén, Robert

, p. 2313 - 2318 (2012)

Four indole-olefin-oxazoline (IndOlefOx) ligands were synthesized and evaluated in Rh-catalyzed reactions between organoboronics and a lactam or a lactone. In addition to the expected conjugate addition products, the formation of significant amounts of Heck-type products was observed. The scope and limitations of these reactions were investigated.
