Check Digit Verification of cas no

The CAS Registry Mumber 903734-72-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,3,7,3 and 4 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 903734-72:
(8*9)+(7*0)+(6*3)+(5*7)+(4*3)+(3*4)+(2*7)+(1*2)=165
165 % 10 = 5
So 903734-72-5 is a valid CAS Registry Number.

Recyclable fluorous organocatalysts promoted three-component reactions of pyruvate, aldehyde and amine at room temperature

Qian, Jin-Long,Yi, Wen-Bin,Cai, Chun

, p. 7100 - 7102 (2013)

A new fluorous imine carbothioate has been prepared as an organocatalyst for the synthesis of pyrrol-2-ones via the cyclo-condensation reaction of aldehydes, amines, and pyruvate at room temperature. The fluorous catalyst can be easily recovered from the reaction mixture by simple fluorous solid-phase extraction (F-SPE) and used for next run reaction without further purification.

1-Butyl-1-methylpyrrolidinium hydrogen sulfate-promoted preparation of 1,5-diaryl-3-(arylamino)-1H-pyrrol-2(5H)-one derivatives

Ghashang, Majid

, p. 2187 - 2195 (2013/06/26)

A convenient preparative approach for synthesis of various 1,5-diaryl-3-(arylamino)-1H-pyrrol-2(5H)-ones promoted by 1-butyl-1- methylpyrrolidinium hydrogen sulfate is developed which involves cyclocondensation of aldehydes with amines and ethyl pyruvate under ambient conditions.
