Check Digit Verification of cas no

The CAS Registry Mumber 332046-11-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,2,0,4 and 6 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 332046-11:
(8*3)+(7*3)+(6*2)+(5*0)+(4*4)+(3*6)+(2*1)+(1*1)=94
94 % 10 = 4
So 332046-11-4 is a valid CAS Registry Number.

Multicomponent Synthesis of 4-Alkyl(Aryl, Hetaryl)-2-alkoxycarbonyl(aroyl, carbamoyl)- 3,6-diamino-5-cyanothieno[2,3-b]pyridines

Dyachenko,Dyachenko,Dorovatovskii,Khrustalev,Nenajdenko

, p. 1435 - 1445 (2019/01/04)

The condensation of malononitrile with hydrogen sulfide and aldehydes in the presence of triethylamine in ethanol at room temperature afforded 4-alkyl(aryl, hetaryl)-2,6-diamino-3,5-dicyano-4H-thiopyrans. Treatment of the latter in situ with alkali in DMF, followed by addition of an alkylating agent, led to the formation of 4-alkyl(aryl, hetaryl)-2-alkoxycarbonyl(aroyl, carbamoyl)-3,6-diamino-5-cyanothieno[2,3-b]- pyridines.

Synthesis of 4-methylmorpholinium 6-amino-3,5-dicyano-4-(furan-2-yl)pyridine-2-thio(seleno)lates and 3-[aryl(hetaryl)]-2-cyanoprop-2-enethioamides by michael reaction

Dyachenko,Ramazanova, E. Yu.,Dyachenko

, p. 1821 - 1825 (2015/02/02)

Michael reaction of dimethyl (furan-2-ylmethylidene)malonate with 2-cyanoethanethio(seleno)amides and 4-methylmorpholine afforded 4-methylmorpholinium 6-amino-3,5-dicyano-4-(furan-2-yl)pyridine-2-thio(seleno)lates via exchange of the CH acid components. Aryl(hetaryl)methylidenemalononitriles reacted with cyanoethanethioamide under analogous conditions to give 3-aryl(hetaryl)-2-cyanoprop-2-enethioamides which were converted into 3-aryl(hetaryl)-2-(1,3-thiazol-2-yl)prop-2-enenitriles according to Hantzsch.
