Check Digit Verification of cas no

The CAS Registry Mumber 51677-40-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,6,7 and 7 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 51677-40:
(7*5)+(6*1)+(5*6)+(4*7)+(3*7)+(2*4)+(1*0)=128
128 % 10 = 8
So 51677-40-8 is a valid CAS Registry Number.

Site-Selective Copper-Catalyzed Azidation of Benzylic C-H Bonds

Site selectivity represents a key challenge for non-directed C-H functionalization, even when the C-H bond is intrinsically reactive. Here, we report a copper-catalyzed method for benzylic C-H azidation of diverse molecules. Experimental and density functional theory studies suggest the benzyl radical reacts with a CuII-azide species via a radical-polar crossover pathway. Comparison of this method with other C-H azidation methods highlights its unique site selectivity, and conversions of the benzyl azide products into amine, triazole, tetrazole, and pyrrole functional groups highlight the broad utility of this method for target molecule synthesis and medicinal chemistry.
