134937-29-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134937-29-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,9,3 and 7 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 134937-29:
(8*1)+(7*3)+(6*4)+(5*9)+(4*3)+(3*7)+(2*2)+(1*9)=144
144 % 10 = 4
So 134937-29-4 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.
