Check Digit Verification of cas no

The CAS Registry Mumber 731-54-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,3 and 1 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 731-54:
(5*7)+(4*3)+(3*1)+(2*5)+(1*4)=64
64 % 10 = 4
So 731-54-4 is a valid CAS Registry Number.

Unexpected formation of 5-alkylidene derivatives of hydantoin from the Michael addition of 4-phenylurazole to fumaric esters

Soltanzadeh, Zahra,Imanzadeh, Gholamhassan,Noroozi-Pesyan, Nader,?ahin, Ertan,Hooshmand, Hemayat

, p. 1736 - 1741 (2016)

An unexpected reaction between 4-phenylurazole and fumaric esters which led to the formation of 5-alkylidene derivatives of hydantoin is described in this paper. The reaction takes place in the presence of tetrabutylammonium bromide (TBAB), and 1,4-diaza-

Action des hydroxyurees sur les maleate et fumarate de methyle. Obtention des carbomethoxy-5 oxa-6 dihydrouraciles; transposition en carbomethoxymethylene-5 hydantoines

Bennouna, Chakib,Petrus, Francoise,Verducci, Jean,Hauw, Christian,Gaultier, Jacques

, p. 2891 - 2897 (2007/10/02)

We describe in this paper the Michael-type addition of hydroxyureas with methyl maleate and fumarate.The cyclization of the ureidoxyester intermediates obtained leads to the isolation of 5-carbomethoxy 6-oxadihydrouracils; their structure is proved by X-ray analysis.These relatively unstable compounds undergo transposition under basic conditions and give 5-carbomethoxyhydantoins.
