1201-15-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1201-15-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,0 and 1 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1201-15:
(6*1)+(5*2)+(4*0)+(3*1)+(2*1)+(1*5)=26
26 % 10 = 6
So 1201-15-6 is a valid CAS Registry Number.

Nucleophilic Cyclization/Electrophilic Substitution of (2,2-Dialkoxyethyl)ureas: Highly Regioselective Access to Novel 4-(Het)arylimidazolidinones and Benzo[ d[[1,3]diazepinones

Smolobochkin, Andrey V.,Gazizov, Almir S.,Otegen, Nazerke K.,Voronina, Julia K.,Strelnik, Anna G.,Samigullina, Aida I.,Burilov, Alexander R.,Pudovik, Michail A.

, p. 3263 - 3271 (2020)

Imidazolidin-2-one and 1,3-benzodiazepin-2-one scaffolds are structural motifs of many biologically active compounds. Herein, we report a highly regioselective acid-catalyzed intramolecular nucleophilic cyclization/intermolecular electrophilic substitutio

Reactions of resorcinol derivatives with 1-methyl-3-phenylimidazol-2-one as a new method for the synthesis of 5-arylimidazolidin-2-ones

Burilov, Alexander R.,Khakimov, Maxim S.,Gazizov, Almir S.,Pudovik, Mikhail A.,Syakaev, Victor V.,Krivolapov, Dmitry B.,Konovalov, Alexander I.

, p. 54 - 55 (2008/09/18)

Substituted imidazolidin-2-ones have been synthesised by the interaction of imidazol-2-one with 2-methylresorcinol and pyrogallol in a chloroform solution in the presence of trifluoroacetic acid.

Efficient solid-phase synthesis of disubstituted 1,3-dihydro-imidazol-2- ones

Rossé, Gérard,Strickler, Julie,Patek, Marcel

, p. 2167 - 2168 (2007/10/03)

A bromoacetal linker was used to achieve the synthesis of ureas on a solid support. The resulting ureido acetals were treated with TFA and were converted in an intramolecular cyclization via N-acyliminium ion to disubstituted 1,3-dihydro-imidazol-2-ones.
