Check Digit Verification of cas no

The CAS Registry Mumber 140458-96-4 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 6 respectively.
Calculate Digit Verification of CAS Registry Number 140458-96:
(8*1)+(7*4)+(6*0)+(5*4)+(4*5)+(3*8)+(2*9)+(1*6)=124
124 % 10 = 4
So 140458-96-4 is a valid CAS Registry Number.

A new methodology for obtaining α-oxo ester equivalents: Sulfanylation of α-sulfonyl carboxylic esters in a solid/liquid phase transfer catalytic system

Wladislaw, Blanka,Marzorati, Liliana,Junior, Nelson Ferreira Claro,Di Vitta, Claudio

, p. 420 - 422 (2007/10/03)

A new, convenient procedure for the synthesis of a wide range of α-methylsulfanyl-α-phenylsulfonyl carboxylic esters has been developed and their facile conversion to the corresponding α-oxo esters demonstrated.

A CONVENIENT SYNTHESIS OF PHENYLSULFONYLALKANOIC ACIDS

Ratajczak, Aleksander,Polanski, Jaroslaw

, p. 1271 - 1275 (2007/10/02)

Ethyl phenylsulfonylacetate is alkylated in high yields with alkyl halides in toluene/K2CO3 two-phase system with TEBA (TBAB) as a catalyst.

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.
