209974-78-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 209974-78-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,9,9,7 and 4 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 209974-78:
(8*2)+(7*0)+(6*9)+(5*9)+(4*7)+(3*4)+(2*7)+(1*8)=177
177 % 10 = 7
So 209974-78-7 is a valid CAS Registry Number.

Ensembles of rings with a coumarin unit. 1. Synthesis of 3-(2-R-thiazol-4-yl)- and 3-(4-R-triazol-2-yl)coumarins

Belokon',Kovalenko,Silin,Nikitchenko

, p. 1167 - 1176 (2007/10/03)

We have synthesized 3-(2-R-thiazol-4-yl)coumarins (R = H, CH3, CH2CN, Ar) by condensation of 3-(α-bromoacetyl)coumarins with thioamides. We obtained 3-(4-R-thiazol-2-yl)coumarins (R = H, Ar) by several methods. By reaction of 2-cyanomethyl-4-phenylthiazole with 2-hydroxybenzaldehydes, we synthesized 2-imino-3-(4-phenylthiazol-2-yl)coumarins, which were converted to the corresponding coumarins by acid hydrolysis. For 3-(2-R-thiazol-4-yl)coumarins (R = CH2CN), we carried out reactions with aromatic aldehydes. We propose alternative methods for synthesis of 2-[2-aryl(hetaryl)-1-cyanoethenyl]-4-(coumarin-3-yl)thiazoles. 1998 Plenum Publishing Corporation.
