134649-71-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134649-71-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,6,4 and 9 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 134649-71:
(8*1)+(7*3)+(6*4)+(5*6)+(4*4)+(3*9)+(2*7)+(1*1)=141
141 % 10 = 1
So 134649-71-1 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.
