Check Digit Verification of cas no

The CAS Registry Mumber 5778-09-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,7,7 and 8 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 5778-09:
(6*5)+(5*7)+(4*7)+(3*8)+(2*0)+(1*9)=126
126 % 10 = 6
So 5778-09-6 is a valid CAS Registry Number.

Copper-catalyzed benzylic C-H oxygenation under an oxygen atmosphere via N-H imines as an intramolecular directing group

Zhang, Line,Ang, Gim Yean,Chiba, Shunsuke

, p. 1622 - 1625 (2011/05/05)

Copper-catalyzed benzylic C-H oxygenation under an oxygen atmosphere was developed starting from carbonitriles and Grignard reagents via N-H imine intermediates. The present process is characterized by the following two-step sequence in a one-pot manner: (1) addition of Grignard reagents to carbonitriles to form N-H imines and (2) benzylic C-H oxygenation (C=O bond formation) triggered by 1,5-hydrogen atom transfer with transient iminyl copper species.
