140458-98-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 140458-98-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,4,5 and 8 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 140458-98:
(8*1)+(7*4)+(6*0)+(5*4)+(4*5)+(3*8)+(2*9)+(1*8)=126
126 % 10 = 6
So 140458-98-6 is a valid CAS Registry Number.

ALKYLATION OF ETHYL ARYLSULFONYLACETATES IN CATALYTIC TWO-PHASE SYSTEM
Ratajczak, Aleksander,Polanski, Jaroslaw
, p. 1963 - 1971 (2007/10/02)
It was found that ethyl arylsulfonylacetates could be easily dialkylated or cyclodialkylated in catalytic two-phase systems with concentrated aqueous sodium hydroxide, undergoing no hydrolysis under the reaction conditions.
