Check Digit Verification of cas no

The CAS Registry Mumber 126019-30-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,0,1 and 9 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 126019-30:
(8*1)+(7*2)+(6*6)+(5*0)+(4*1)+(3*9)+(2*3)+(1*0)=95
95 % 10 = 5
So 126019-30-5 is a valid CAS Registry Number.

Cis-trans photoisomerization of a p-styrylstilbene, a one- and twofold adiabatic process

Sandros, Kjell,Sundahl, Mikael,Wennerstr?m, Olof,Norinder, Ulf

, p. 3082 - 3086 (1990)

The mechanism of the Z/E photoisomerization of a p-styrylstilbene has been studied by steady state and time-resolved fluorescence measurements combined with isomerization quantum yield determinations. It was found that on excitation of the Z,Z isomer both the isomers, Z,E and E,E, are produced initially, mainly by adiabatic processes on the singlet excited surface. Quantum mechanical calculations give surface profiles supporting the adopted mechanism.
