64809-18-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 64809-18-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,8,0 and 9 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 64809-18:
(7*6)+(6*4)+(5*8)+(4*0)+(3*9)+(2*1)+(1*8)=143
143 % 10 = 3
So 64809-18-3 is a valid CAS Registry Number.

A new and general synthesis of chiral β-ketosulfoxides by reaction of (+)-(R)-methyl p-tolyl sulfoxide with nitriles
Vleggaar, Robert,Zeevaart, Jacob G.
, p. 9301 - 9303 (2007/10/03)
The nitrile functional group is efficiently transformed into the β-ketosulfoxide moiety by reaction with the anion formed from (+)-(R)-methyl p-tolyl sulfoxide and aqueous acidic work-up of the reaction.
