Check Digit Verification of cas no

The CAS Registry Mumber 189046-99-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,0,4 and 6 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 189046-99:
(8*1)+(7*8)+(6*9)+(5*0)+(4*4)+(3*6)+(2*9)+(1*9)=179
179 % 10 = 9
So 189046-99-9 is a valid CAS Registry Number.

Sequenced Reactions with Samarium(II) Iodide. Sequential Nucleophilic Acyl Substitution/Ketyl Olefin Coupling Reactions for the Preparation of Oxygen Heterocycles

Molander, Gary A.,Harris, Christina R.

, p. 2944 - 2956 (2007/10/03)

Samarium(II) iodide has been employed to promote a sequential intramolecular nucleophilic acyl substitution/intramolecular ketyl olefin coupling cyclization sequence to provide bicyclic, tricyclic, and spiro-fused oxygen heterocycles in excellent yield and with high diastereoselectivity.
