Check Digit Verification of cas no

The CAS Registry Mumber 1402160-73-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,2,1,6 and 0 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1402160-73:
(9*1)+(8*4)+(7*0)+(6*2)+(5*1)+(4*6)+(3*0)+(2*7)+(1*3)=99
99 % 10 = 9
So 1402160-73-9 is a valid CAS Registry Number.

Rhodium-catalyzed regioselective carboacylation of olefins: A C-C bond activation approach for accessing fused-ring systems

Xu, Tao,Dong, Guangbin

, p. 7567 - 7571 (2012/09/22)

Cut and sew: A rhodium-catalyzed regioselective carboacylation reaction of benzocyclobutenones was developed (see scheme). Directed by the pendant olefins, the C1-C2 bond is selectively cleaved rather than the C1-C8 bond. Subsequent alkene insertion leads to complex fused-ring systems. This reaction provides facile access to natural-product-like polycyclic structures in a chemoselective and atom-economic fashion. Copyright
