Check Digit Verification of cas no

The CAS Registry Mumber 52962-92-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,9,6 and 2 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 52962-92:
(7*5)+(6*2)+(5*9)+(4*6)+(3*2)+(2*9)+(1*2)=142
142 % 10 = 2
So 52962-92-2 is a valid CAS Registry Number.

Domino synthesis of pyrimido and imidazoquinazolinones

Fathalla, Walid,Nofal, Eman Y.,El-Moneim, Mohamed Abd

, p. 1266 - 1274 (2020/01/21)

A simple method for the synthesis of N-alkyl-2-arylquinazolin-4-amines, methyl 4-((2-arylquinazolin-4-yl)amino) butanoates, 6-aryl-2,3-dihydro-4H-pyrimido[1,2-c]quinazolin-4-ones, and 5-arylimidazo[1,2-c]quinazolin-3(2H)-ones has been described. It involves a simple reaction of N-(2-cyanophenyl)-substitutedbenzimidoyl chlorides with alkylamine, γ-aminobutyric acid, β-alanine, l-alanine, and glycine methyl esters hydrochloride in acetonitrile to afford the desired compounds after a series of instantaneous reactions that include Dimroth rearrangement. The reaction involves reflux for 12 hours, simple addition of reagents to an in situ generated benzimidoyl chloride, and simple workup, to form 21 examples of pure compounds in high yields. The active intermediate N-(2-cyanophenyl)-substitutedbenzimidoyl chlorides were formed by the reaction of N-(2-cyanophenyl)-substitutedbenzamides with thionyl chloride in a one-pot strategy. The alternative method described for this preparation deals with an exhausting multistep reactions starting from anthranilic acid.

One-pot synthesis of quinazolinone and benzamide derivatives using SBA-Pr-SO3H as a nanoporous heterogeneous acid catalyst

Nahad, Monireh Shakiba,Ziarani, Ghodsi Mohammadi

, p. 1597 - 1603 (2014/05/06)

A series of quinazolinone and benzamide derivatives have been efficiently synthesized in good to excellent yields via the reaction of 2-aminobenzamide and aromatic benzoyl chlorides under solvent-free conditions using SBA-Pr-SO 3H as a nano solid acid catalyst.

Mechanism of alkaline cyclization of 2-(substituted benzamido)benzamides to 4-quinazolinones

Gardner,Kanagasooriam,Smyth,Williams

, p. 6245 - 6250 (2007/10/02)

The title amides cyclize rapidly to the corresponding quinazolin-4-ones in aqueous alkaline solution at 25°C; the pseudo-first-order rate constants fit the empirical equation k(obs) = k(max) [OH-]/(K(m) + [OH-] + [OH-]sup
