Check Digit Verification of cas no

The CAS Registry Mumber 498534-34-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,8,5,3 and 4 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 498534-34:
(8*4)+(7*9)+(6*8)+(5*5)+(4*3)+(3*4)+(2*3)+(1*4)=202
202 % 10 = 2
So 498534-34-2 is a valid CAS Registry Number.

Synthesis of 2-benzyl-1,10-phenanthrolines substituted by sulfoxide or sulfone groups as potential photochromic compounds

Heynderickx, Arnault,Samat, Andre,Guglielmetti, Robert

, p. 1747 - 1751 (2007/10/03)

New 2-benzyl-1,10-phenanthrolines, substituted at the 2′ position by electron-withdrawing groups, were synthesized through nucleophilic substitution involving 2-chloro-1,10-phenanthroline and substituted benzyllithiums, respectively. The expected reversible photoinduced proton transfer reaction of such compounds were studied.
