878209-81-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 878209-81-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,8,2,0 and 9 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 878209-81:
(8*8)+(7*7)+(6*8)+(5*2)+(4*0)+(3*9)+(2*8)+(1*1)=215
215 % 10 = 5
So 878209-81-5 is a valid CAS Registry Number.

Catalytic four-component assembly based on allenylboronate platform: New access to privileged allylic amine structures

Tonogaki, Keisuke,Itami, Kenichiro,Yoshida, Jun-Ichi

, p. 1464 - 1465 (2006)

We developed a novel palladium-catalyzed four-component assembly based on allenylboronate platform, by which privileged allylic amine structures can be constructed in a regioselective, stereoselective, and diversity-oriented manner. The boryl group acts not only as a useful group that can be transformed to various functional groups afterward but also as a stereochemical controller in the generation of key (π-allyl)palladium intermediates. A short synthesis of rolipram (selective phosphodiesterase-4 inhibitor) is also demonstrated. Copyright
