137345-48-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 137345-48-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,3,4 and 5 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 137345-48:
(8*1)+(7*3)+(6*7)+(5*3)+(4*4)+(3*5)+(2*4)+(1*8)=133
133 % 10 = 3
So 137345-48-3 is a valid CAS Registry Number.

Scope and limitations in the use of α-silyl and α-stannyl sulfones as latent α-sulfonyl anions

Lamothe,Anderson,Fuchs

, p. 1675 - 1693 (1991)

Three methods for the regeneration of α-sulfonyl anions from α-silyl sulfones and α-stannyl sulfones are investigated. These methods include: (1) treatment of α-silyl sulfones with electrophiles (aldehydes and acid halides) in the presence of fluoride ion; (2) reaction of α-silyl sulfones with n-butyllithium which produces an α-silyl anion via a migration of the -SiMe3 group from the α-position to the ortho-position of the phenyl sulfones; and (3) direct transmetalation of α-stannyl sulfone by treatment with n-butyllithium. The addition of cerium [III] chloride is shown to substantially decrease enolization problems associated with addition of α-sulfonyl anions to carbonyl compounds bearing enolizable protons.
