1257064-35-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1257064-35-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,7,0,6 and 4 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1257064-35:
(9*1)+(8*2)+(7*5)+(6*7)+(5*0)+(4*6)+(3*4)+(2*3)+(1*5)=149
149 % 10 = 9
So 1257064-35-9 is a valid CAS Registry Number.

New chiral ionic liquids based on enantiopure sulfate and sulfonate anions for chiral recognition
Winkel, Andreas,Wilhelm, Rene
experimental part, p. 5817 - 5824 (2011/02/21)
The synthesis of new chiral ionic liquids with chiral anions is described. Chiral sulfate anions were prepared from alcohols of the "chiral pool" in good yields. Subsequent ion metathesis resulted in new salts with tetrabutylphosphonium and 1-butyl-3-meth
