Check Digit Verification of cas no

The CAS Registry Mumber 13950-05-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,9,5 and 0 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 13950-05:
(7*1)+(6*3)+(5*9)+(4*5)+(3*0)+(2*0)+(1*5)=95
95 % 10 = 5
So 13950-05-5 is a valid CAS Registry Number.

Reductive lithiation of alkyl phenyl sulfides in diethyl ether. A ready access to α,α-dialkylbenzyllithiums

Screttas, Constantinos G.,Heropoulos, Georgios A.,Micha-Screttas, Maria,Steele, Barry R.,Catsoulacos, Dimitrios P.

, p. 5633 - 5635 (2003)

Diethyl ether is a convenient solvent for the conversion of benzylic phenyl sulfides to the corresponding organolithiums by an uncatalyzed reductive metalation, while catalysis by naphthalene is required to achieve the same reaction for alkyl phenyl sulfides. The addition of magnesium 2-ethoxyethoxide to solutions of unstable alkyllithiums prepared in this way provides storable reagents.
