126865-31-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 126865-31-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,8,6 and 5 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 126865-31:
(8*1)+(7*2)+(6*6)+(5*8)+(4*6)+(3*5)+(2*3)+(1*1)=144
144 % 10 = 4
So 126865-31-4 is a valid CAS Registry Number.

Heterocyclic Compounds from 2-(Alkoxycarbonylcyanomethylene)-1,3-dioxolanes

Neidlein, Richard,Kikelj, Danijel,Kramer, Walter

, p. 1335 - 1340 (2007/10/02)

2-(Alkoxycarbonylcyanomethylene)-1,3-dioxolanes reacted with hydrazines and hydroxylamine to yield 1-substituted 4-alkoxycarbonyl-5-amino-3-(2'-hydroxyethoxy)pyrazoles and 4-alkoxycarbonyl-5-amino-3-(2'-hydroxyethoxy)isoxazoles respectively.With guanidine and benzamidine 2-substituted (R = NH2, C6H5) 5-cyano-6-(2'-hydroxyethoxy)pyrimidin-4-ones were obtained.Reaction of 2-(cyanomethoxycarbonylmethylene)-1,3-dioxolane with 1,3-diaminopropane afforded 2-(cyanomethoxycarbonylmethylene)-1,3-hexahydropyrimidine whereas treatment of the same compound with 4,5-dimethyl-1,2-phenylenediamine gave 2-(cyanomethoxycarbonylmethylene)-5,6-benzimidazoline.The structures of pyrazoles and pyrimidones were assigned on the basis of (1)H- and (13)C--nOe experiments.
