2687-40-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2687-40-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,8 and 7 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 2687-40:
(6*2)+(5*6)+(4*8)+(3*7)+(2*4)+(1*0)=103
103 % 10 = 3
So 2687-40-3 is a valid CAS Registry Number.

Synthesis of methyl 5(6)-(4-aminophenoxy)-and 5(6)-(2-aminophenoxy)-2- benzimidazolyl carbamates and their biological properties

Pilyugin,Mikhailyuk,Kosareva,Chikisheva,Kiseleva,Kuznetsova,Vorobyeva,Klimakova

, p. 1154 - 1160 (2003)

A procedure was developed for preparation of methyl 5(6)-(4-aminophenoxy)- and 5(6)-(2-aminophenoxy)-2-benzimidazolyl carbamates by reaction of 3,4,4′-triaminodiphenyl or 3,4,2′-triaminodiphenyl ethers respectively with methyl cyanocarbamate in water solution in the presence of 7-10 molar excess of acetic acid. The helminthicidal properties, embryotoxicity, and overall toxicity of compounds obtained were estimated.

2-Carbomethoxy-3-hydroxyquinoxaline-di-N-oxide as a novel ligand for the copper-catalyzed coupling reaction of phenols and aryl halides

Qiu, Yatao,Jia, Weijun,Yao, Zhiyi,Wu, Fanhong,Jiang, Sheng

, p. 1502 - 1510 (2013/05/08)

2-Carbomethoxy-3-hydroxyquinoxaline-di-N-oxide was identified as an efficient novel ligand for the copper-catalyzed coupling of aryl halides with various phenols under mild conditions. The catalytic system shows great functional-group tolerance and excellent reactive selectivity.

Synthesis and structure of Di[methoxy(ethoxy)carbonylamino-1H-benzimidazol- 5-yl] ethers

Pilyugin,Sapozhnikov,Kiseleva,Sapozhnikova,Vorob'eva,Klimakova

, p. 1509 - 1513 (2007/10/03)

A procedure was developed for preparing di[methoxy(ethoxy)carbonylamino-1H- benzimidazol-5-yl] ethers by the reaction of methyl or ethyl chloroformate with sodium cyanamide, followed by the reaction of the resulting methyl or ethyl cyanocarbamate with 4-(3,4-diaminophenoxy)-1,2-phenylenediamine in acidic solution. 2005 Pleiades Publishing, Inc.
