669078-51-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 669078-51-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,9,0,7 and 8 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 669078-51:
(8*6)+(7*6)+(6*9)+(5*0)+(4*7)+(3*8)+(2*5)+(1*1)=207
207 % 10 = 7
So 669078-51-7 is a valid CAS Registry Number.

Scope of Palladium-Catalyzed Alkylative Ring Opening
Lautens, Mark,Hiebert, Sheldon
, p. 1437 - 1447 (2004)
We have explored the scope of the palladium-catalyzed nucleophilic ring opening methodology. New highly selective and highly active catalysts have been found for the ring opening of oxabenzonorbornadienes. Employing these catalysts, the addition of variou
