851345-56-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 851345-56-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,1,3,4 and 5 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 851345-56:
(8*8)+(7*5)+(6*1)+(5*3)+(4*4)+(3*5)+(2*5)+(1*6)=167
167 % 10 = 7
So 851345-56-7 is a valid CAS Registry Number.

Switching of intramolecular charge transfer in cruciforms: Metal ion sensing
Wilson, James N.,Bunz, Uwe H. F.
, p. 4124 - 4125 (2005)
Three different cruciforms containing the 1,4-bis-4′-pyridylethynyl-2,5-distyrylbenzene or the 1,4-bis-phenylethynyl-2,5-distyrylbenzene unit were synthesized and investigated with respect to their metal sensing properties. Upon addition of metal cations
