93681-98-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 93681-98-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,6,8 and 1 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 93681-98:
(7*9)+(6*3)+(5*6)+(4*8)+(3*1)+(2*9)+(1*8)=172
172 % 10 = 2
So 93681-98-2 is a valid CAS Registry Number.

Studies on Chiral Organo-Sulfur Compounds. II. Stereochemistry of Thermal Chiral Allyl Sulfinate-Sulfone Rearrangements

Hiroi, Kunio,Kitayama, Ryuichi,Sato, Shuko

, p. 2628 - 2638 (2007/10/02)

A highly efficient and general synthetic route to optically active sulfinates by the stereospecific boron trifluoride etherate-catalyzed esterification of sulfinamides was developed.Dramatic solvent effects were observed in the thermal transformation of allyl sulfinate derivatives to sulfones.Heating of chiral trans- and cis-allyl sulfinates, (S)-(-)-3a,c,e and (S)-(-)-3b,d,f, in N,N-dimethylformamide at 90-120 deg C provided chiral sulfones (S)-(+)- and (R)-(-)-5,6,7 in good yields, respectively, with exceedingly high stereospecificity. Keywords - asymmetric transfer; stereospecificity; chiral allyl sulfinate; chiral allyl sulfone; boron trifluoride etherate; thermolysis
