Check Digit Verification of cas no

The CAS Registry Mumber 1252786-43-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,2,7,8 and 6 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1252786-43:
(9*1)+(8*2)+(7*5)+(6*2)+(5*7)+(4*8)+(3*6)+(2*4)+(1*3)=168
168 % 10 = 8
So 1252786-43-8 is a valid CAS Registry Number.

Photoisomerization of ionic liquid ammonium cinnamates: One-pot synthesis-isolation of Z-cinnamic acids

Salum, Maria L.,Robles, Cecilia J.,Erra-Balsells, Rosa

supporting information; experimental part, p. 4808 - 4811 (2011/01/03)

Photoisomerization presents the only direct method for contra-thermodynamic E-Z isomerization of olefins. Synthetic applications of this method have been limited by its reversible nature, which leads to a photostationary-state mixture of both isomers. For the first time, a highly efficient one-pot preparation-isolation of solid ionic liquid Z-cinnamic acids by photoisomerization in acetonitrile solution of ionic liquid E-cinnamic acids is described.
