82947-19-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 82947-19-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,9,4 and 7 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 82947-19:
(7*8)+(6*2)+(5*9)+(4*4)+(3*7)+(2*1)+(1*9)=161
161 % 10 = 1
So 82947-19-1 is a valid CAS Registry Number.

Hydrolysis of Aryl Derivates of Malonaldehyde Dianil. III

Ono, Machiko,Tamura, Shinzo

, p. 1453 - 1462 (2007/10/02)

The reaction sequence of hydrolysis of N-acyl derivates of malonaldehyde dianil was examined.Hydrichloric acid-catalysed hydrolysis occured at the imino group to form arylamine and β-(N-acylarylamino)acrolein; the latter compound is not stable in acid solution.In the case of 1-(N-phenylcarbamoyl-p-methylphenylamino)-3-(p-methylphenylimino)-1-propene, hydrolysis occured at both the imino and the carbamoyl groups.Buffer catalysed hydrolysis occured at the imino group, and the resulting β-(N-acylarylamino)acrolein and arylamine reacted to form β-arylaminoacrolein and N-arylamine.The aminolysis reaction was suppressed in hydrochloric acid-catalysed hydrolysis.Alkaline hydrolysis of N-acyl derivates of malonaldehyde dianil and of β-arylaminoacrolein occured at the amide carbonyl group except in the case of 1-(N-tosyl-p-methylphenylamino)-3-(p-methylphenylimino)-1-propene.N-tosyl-p-toluidine was obtained in this case.Keywords--hydrolysis; malonaldehyde dianil; β-arylaminoacrolein; 1-(N-acylarylamino)-3-arylamino-1-propene; β-(N-acylarylamino)acrolein; 1-(N-tosyl-p-methylphenyilamino)-3-(p-methylphenylimino)-1-propene; 1-(N-tosyl-p-methylphenylamino)-3-(p-methylphenyilimino-1-butene; β-(N-tosyl-p-toluidino)acrolein; 4-(N-tosyl-p-toluidino)-3-buten-2-one
