74428-56-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 74428-56-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,4,2 and 8 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 74428-56:
(7*7)+(6*4)+(5*4)+(4*2)+(3*8)+(2*5)+(1*6)=141
141 % 10 = 1
So 74428-56-1 is a valid CAS Registry Number.

Nitrogen-15 NMR Evidence for the Structures of N-9 H-Xanthen-9-yl- and N,N'-Di-9H-xanthen-9-yl-Ureas

Coxon, Bruce,Fatiadi, Alexander J.,Cohen, Alex,Hertz, Harry S.,Schaffer, Robert

, p. 187 - 192 (2007/10/02)

A new monoxanthen-9-yl derivative of urea has been synthesized and the structure of this product (N-9H-xanthen-9-ylurea) and that of the previously known N,N'-di-9H-xanthen-9-ylurea have been proved by 15N NMR and other spectroscopic techniques.A series of 13C and 15N labeled urea derivatives has been prepared and the utility of their 13C and 15N chemical shifts and coupling constants in the structural analysis of urea derivatives has been investigated.
