Check Digit Verification of cas no

The CAS Registry Mumber 352532-70-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,5,2,5,3 and 2 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 352532-70:
(8*3)+(7*5)+(6*2)+(5*5)+(4*3)+(3*2)+(2*7)+(1*0)=128
128 % 10 = 8
So 352532-70-8 is a valid CAS Registry Number.

Novel perylene chromophores obtained by a facile oxidative cyclodehydrogenation route

Wehmeier, Mike,Wagner, Manfred,Muellen, Klaus

, p. 2197 - 2205 (2007/10/03)

New perylene chromophores, phenyl-substituted diindeno[1,2,3-cd: 1′,2′,3′-lm]perylenes 5a,b and 4,4′,7,7′-tetraphenyldiacenaphtho[1,2- k:1′,2′,k′]diindeno[1,2,3-cd:1′,2′,3′- me]perylenes 22a,b, have been synthesized from substituted fluoranthene derivatives 3 a,b and 4 a,b by means of a surprisingly simple oxidative cyclodehydrogenation reaction. The resulting chromophores, when substituted with alkyl chains at the periphery, show good solubility in organic solvents, and a full characterization of the novel red, green, and blue dyes by field-desorption mass spectrometry, UV/Vis and 1H and 13C NMR spectroscopy becomes possible.
