91077-71-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 91077-71-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,0,7 and 7 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 91077-71:
(7*9)+(6*1)+(5*0)+(4*7)+(3*7)+(2*7)+(1*1)=133
133 % 10 = 3
So 91077-71-3 is a valid CAS Registry Number.

Arylsulfonylpyrroles from reaction of tosylmethyl isocyanide (tosmic) with 3-arylsulfonyl acrylates as michael acceptors

Di Santo, Roberto,Costi, Roberta,Massa, Silvio,Artico, Marino

, p. 1801 - 1815 (2007/10/03)

Ethyl 3-(arylthio)acrylates did not react with α-alkali metalated tosylmethyl isocyanide (TosMIC) to afford 4-(arylthio)pyrrole-3-carboxylic acid ethyl esters. Oxidation of thioethers to sulfones generated reactive 3- (arylsulfonyl) acrylates, which promptly underwent cycloaddition with TosMIC in the presence of base giving ethyl 4-(arylsulfonyl)pyrrole-3-carboxylates. Contrary to expectation, the use of ethyl 3-(5-chloro-2- nitrophenylsulfonyl)acrylate led to ethyl ester of 5-tosylpyrrole-3- carboxylic acid instead of the expected ethyl 4-(5-chloro-2- nitrophenylsulfonyl)pyrrole-3-carboxylate.
