Check Digit Verification of cas no

The CAS Registry Mumber 35218-40-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,5,2,1 and 8 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 35218-40:
(7*3)+(6*5)+(5*2)+(4*1)+(3*8)+(2*4)+(1*0)=97
97 % 10 = 7
So 35218-40-7 is a valid CAS Registry Number.

Copper Catalyzed Oxidative C-C Bond Cleavage of 1,2-Diketones: A Divergent Approach to 1,8-Naphthalimides, Biphenyl-2,2′-dicarboxamides, and N-Heterocyclic Amides

Sakhare, Priyanka R.,Subramanian, Parthasarathi,Kaliappan, Krishna P.

, p. 2112 - 2125 (2019)

We report here a simple and efficient copper catalyzed oxidative C-C bond cleavage of stable aromatic cyclic-fused and acyclic 1,2-diketones to deliver amides and imides in high yields. This newly developed protocol provides an excellent tool to transform structurally different 1,2-diketones into different products under the same reaction conditions. The key synthetic features of this methodology are the formation of 1,8-naphthalimides and biphenyl-2,2′-dicarboxamide motifs in high yields. The fluorescent studies of 1,8-naphthalimide derivatives were also carried out in order to show the potential application of these scaffolds.
