Check Digit Verification of cas no

The CAS Registry Mumber 1227008-49-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,7,0,0 and 8 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1227008-49:
(9*1)+(8*2)+(7*2)+(6*7)+(5*0)+(4*0)+(3*8)+(2*4)+(1*9)=122
122 % 10 = 2
So 1227008-49-2 is a valid CAS Registry Number.

Acid-base responsive photoelectric conversion of a hydroxyazobenzene- appended bipyridine-copper complex system

Umeki, Satoshi,Kume, Shoko,Nishihara, Hiroshi

, p. 204 - 205 (2010)

We report the synthesis of a new 4-hydroxyazobenzene-appended bipyridine complex of copper, [Cu(oAB-2OH)2]BF4, which exhibits a reversible acid-base responsive redox-active photoisomerization reaction. The acid-base modulation of the photoisomerization reaction permits ON/OFF toggling of the photoelectric conversion in devices containing this complex by the addition of small quantities of acid or base in the presence of 4,4′-bis(ethoxycarbonyl)-2,2′-bipyridine, bpy-2COOEt.
