Check Digit Verification of cas no

The CAS Registry Mumber 850426-03-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,0,4,2 and 6 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 850426-03:
(8*8)+(7*5)+(6*0)+(5*4)+(4*2)+(3*6)+(2*0)+(1*3)=148
148 % 10 = 8
So 850426-03-8 is a valid CAS Registry Number.

Ketyl-allene cyclizations promoted by samarium(II) iodide

Molander, Gary A.,Cormier, Elizabeth Pollina

, p. 2622 - 2626 (2005)

(Chemical Equation Presented) Samarium(II) iodide has proven to be an effective reagent for intramolecular reductive coupling Sreactions. Previous investigations of intramolecular ketyl-olefin coupling reactions provided carbocycles in excellent yield and good diastereoselectivity. This method has been extended to ketyl cyclizations with allenes. Substrates leading to both carbocycles and heterocycles in a selective manner are explored.
