139420-57-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 139420-57-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,4,2 and 0 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 139420-57:
(8*1)+(7*3)+(6*9)+(5*4)+(4*2)+(3*0)+(2*5)+(1*7)=128
128 % 10 = 8
So 139420-57-8 is a valid CAS Registry Number.

Microwave Assisted Synthesis of Fused Thiazoles in Multicomponent System and Their in vitro Antitumor, Antioxidant, and Antimicrobial Activities

El-Borai, Mohamed A.,Rizk, Hala F.,Ibrahim, Seham A.,El-Sayed, Hatem F.

, p. 1031 - 1041 (2017)

A novel series of thiazolopyrimidines, thiazolopyrimidinones, imidazolothiazoles, and 1-thiazole-5-pyrazolone was synthesized under microwave irradiation. Most of the synthesized compounds were screened in vitro antitumor, antioxidant, and antimicrobial activities.

SYNTHESIS AND PROPERTIES OF 1,3,4-THIADIAZINE DERIVATIVES. 1. INVESTIGATION OF THE CONDENSATION OF SUBSTITUTED PHENACYL BROMIDES AND BROMOACETYLPYRIDINES WITH THIOSEMICARBAZIDE

Novikova, A. P.,Perova, N. M.,Egorova, L. G.,Bragina, E. I.

, p. 666 - 668 (2007/10/02)

2-Amino-5-aryl(pyridyl)-6H-1,3,4-thiadiazines and isomeric 2-hydrazino-4-aryl(pyridyl)thiazoles, the ration of which depends on the reaction conditions, were obtained by the reaction of substituted phenacyl bromides and bromoacetylpyridines with thiosemicarbazide.
