148930-27-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 148930-27-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,8,9,3 and 0 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 148930-27:
(8*1)+(7*4)+(6*8)+(5*9)+(4*3)+(3*0)+(2*2)+(1*7)=152
152 % 10 = 2
So 148930-27-2 is a valid CAS Registry Number.

SYNTHESIS AND BIOLOGICAL ACTIVITY OF 1,5-DIARYL-3-ARYLAMINO-4-CARBOXYMETHYL-2,5-DIHYDRO-2-PYRROLONES AND 1,5-DIARYL-4-CARBOXYMETHYLTETRAHYDROPYRROLE-2,3-DIONES

REACTION OF α-KETOGLUTARIC ACID WITH SCHIFF BASES

Gein, V. L.,Popov, A. V.,Andreichikov, Yu. S.

, p. 2291 - 2295 (2007/10/02)

1,5-Diaryl-3-arylamino-4-carboxymethyl-2,5-dihydropyrrol-2-ones were synthesized in the reaction of α-ketoglutaric acid with Schiff bases. Their hydrolysis in concentrated hydrochloric acid results in 1,5-diaryl-3-hydroxy-4-carboxymethyl-2,5-dihydropyrrol-2-ones. These latter are converted into the initial compounds when treated with arylamines. The heating of 1,5-diaryl-4-methoxycarbonyl-2,5-dihydropyrrol-2-ones and their 3-arylamino derivatives above the melting point leads to their decarboxylation, while the treatment with diphenyldiazomethane converts them into the corresponding benzhydryl ethers.
