Check Digit Verification of cas no

The CAS Registry Mumber 142452-40-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,4,5 and 2 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 142452-40:
(8*1)+(7*4)+(6*2)+(5*4)+(4*5)+(3*2)+(2*4)+(1*0)=102
102 % 10 = 2
So 142452-40-2 is a valid CAS Registry Number.

SOLID-STATE PHOTOREACTIVITY OF ORTHO-DISTYRYLAROMATIC COMPOUNDS

Boehm, Arno,Adam, Martin,Mauermann, Heike,Stein, Stefan,Muellen, Klaus

, p. 2795 - 2799 (2007/10/02)

While 2,2'-distyrylbiphenyl (1) shows no solid-state photoreactivity, the tert.-butyl substituted derivative 2 is quantitatively transformed into the intramolecular cycloadduct 4.In contrast, 1,2-distyrylbenzene (5) exhibits a strong tendency toward photopolymerization in the crystalline state, while the tert.-butylated derivative 7 proves to be photostable.
