60012-73-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 60012-73-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,0,0,1 and 2 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 60012-73:
(7*6)+(6*0)+(5*0)+(4*1)+(3*2)+(2*7)+(1*3)=69
69 % 10 = 9
So 60012-73-9 is a valid CAS Registry Number.

Facile synthesis of vinyl sulfones from β-bromo alcohols

Lee, Jae Wook,Lee, Chi-Wan,Jung, Jin Hang,Oh, Dong Young

, p. 2897 - 2902 (2007/10/03)

Vinyl sulfones are synthesized in good yields by dehydration of β- hydroxy sulfones derived from β-bromo alcohols.

DIANIONS OF β-HYDROXY SULFONES: NEW AND GENERAL APPROACH TO SELECTIVE SYNTHESIS OF 2(5H)-FURANONES

Tanaka, Kazuhiko,Ootake, Kazuhiko,Imai, Keisuke,Tanaka, Nobuo,Kaji, Aritsune

, p. 633 - 636 (2007/10/02)

Dianions derived from β-hydroxy sulfones are highly reactive toward a variety of electrophiles including alkyl halides, carbonyl compounds, and sodium iodoacetate.A convenient synthetic method for 4-alkyl- and 5-alkyl-2(5H)-furanones has been developed by using these dianions.A new synthetic approach to trans,3,4-bis(3-hydroxybenzyl)dihydro-2(3H)-furanone, the first lignan found in humans, via a facile reduction of 2(5H)-furanone with Mg-methanol is also described.
