137056-26-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 137056-26-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,0,5 and 6 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 137056-26:
(8*1)+(7*3)+(6*7)+(5*0)+(4*5)+(3*6)+(2*2)+(1*6)=119
119 % 10 = 9
So 137056-26-9 is a valid CAS Registry Number.

The Reaction of 2-Aminothiophene-3-carbonitriles with Heterocumulenes

Gewald, K.,Jeschke, T.,Gruner, M.

, p. 229 - 236 (2007/10/02)

The reaction of 2-aminothiophene-3-carbonitriles (1) with phenyl isothiocyanate does not yield the expected thienopyrimidine derivatives but the substituted dithienopyrimidopyrimid-7-thiones (4).The compounds 4 also may be synthesized from 1 and thiophosgene.Analogously, from 1 and phenyl isocyanate the substituted dithienopyrimidopyrimid-7-ones (9) arise in small yields.They are better obtainable from 1 and phosgene.Carbon disulphide reacts with 1 in pyridine to form a mixture of the thienopyrimid-2,4-dithione (10) and the condensed compound 4.The ratio of of products depends on the substituents in the 4,5-position of 1.The structures are investigated by n.m.r.-spectroscopy.

Interaction of heterothiocumulenes with 2-amino-3-cyanothiophenes: Formation of thienopyrimidines

Sukumaran, P.,Rajasekharan, K. N.

, p. 642 - 646 (2007/10/02)

Thieno-fused(1,3)-thiazine, 4-imino-2-thioxo-2,4-dihydro-1H-thieno(1,3)-thiazine (2) has been directly synthesised by the reaction of o-aminonitrile (1a) with carbon disulphide.Thiazine (2) on reaction with primary aromatic amines leads to thieno2
