Check Digit Verification of cas no

The CAS Registry Mumber 34999-46-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,9,9 and 9 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 34999-46:
(7*3)+(6*4)+(5*9)+(4*9)+(3*9)+(2*4)+(1*6)=167
167 % 10 = 7
So 34999-46-7 is a valid CAS Registry Number.

Activation of C-H Activation: The Beneficial Effect of Catalytic Amount of Triaryl Boranes on Palladium-Catalyzed C-H Activation

Tischler, Orsolya,Bokányi, Zsófia,Novák, Zoltán

, p. 741 - 746 (2016)

Herein we report a novel approach to the acceleration of palladium-catalyzed C-H activation reactions. We demonstrated that the utilization of electron-deficient triaryl boranes as Lewis acidic cocatalysts of palladium enables the directed cross dehydrogenative coupling of aldehydes and anilides under mild reaction conditions. Study of the kinetic profile of the transformation reveals a unique, unexpectedly long induction period of the transformation.
