Check Digit Verification of cas no
The CAS Registry Mumber 99186-05-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,1,8 and 6 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 99186-05:
(7*9)+(6*9)+(5*1)+(4*8)+(3*6)+(2*0)+(1*5)=177
177 % 10 = 7
So 99186-05-7 is a valid CAS Registry Number.

Cyclopentane Formation from Flexible Precursors Using Samarium(II) Reagents
Aretz, Christopher D.,Escobedo, Humberto,Cowen, Bryan J.
, p. 1880 - 1884 (2018/05/09)
Three efficient methods for five-membered ring carbocycle synthesis have been developed from simple starting materials using samarium(II) reagents. A Reformatsky aldol reaction proceeded efficiently with samarium(II) iodide using lithium bromide as an additive. A new intramolecular alkylation of a samarium enolate was realized with a pendant sulfonate ester leaving group. Pinacol cyclization of a simple diketone was also demonstrated giving a diol product in high stereoselectivity. A promising lead result has been established demonstrating enantioselectivity in a chiral ligand controlled Reformatsky aldol reaction.
