109520-78-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109520-78-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,5,2 and 0 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 109520-78:
(8*1)+(7*0)+(6*9)+(5*5)+(4*2)+(3*0)+(2*7)+(1*8)=117
117 % 10 = 7
So 109520-78-7 is a valid CAS Registry Number.

β,β-Dinitrostyrenes: Specificity of synthesis and structure
Berestovitskaya,Pabolkova,Belyakov,Trukhin
, p. 1912 - 1918 (2008/09/17)
An improved procedure was developed for the synthesis of β,β-dinitrostyrenes, which increased the yield and reproducibility and made the products more accessible from the preparative viewpoint. Complex analysis of the spectral data (IR, UV, 1H
