Check Digit Verification of cas no

The CAS Registry Mumber 1428157-04-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,8,1,5 and 7 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1428157-04:
(9*1)+(8*4)+(7*2)+(6*8)+(5*1)+(4*5)+(3*7)+(2*0)+(1*4)=153
153 % 10 = 3
So 1428157-04-3 is a valid CAS Registry Number.

Directing group enhanced carbonylative ring expansions of amino-substituted cyclopropanes: Rhodium-catalyzed multicomponent synthesis of N-heterobicyclic enones

Shaw, Megan H.,Melikhova, Ekaterina Y.,Kloer, Daniel P.,Whittingham, William G.,Bower, John F.

, p. 4992 - 4995 (2013/05/22)

Aminocyclopropanes equipped with suitable N-directing groups undergo efficient and regioselective Rh-catalyzed carbonylative C-C bond activation. Trapping of the resultant metallacycles with tethered alkynes provides an atom-economic entry to diverse N-heterobicyclic enones. These studies provide a blueprint for myriad N-heterocyclic methodologies.
