80663-40-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80663-40-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,6,6 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 80663-40:
(7*8)+(6*0)+(5*6)+(4*6)+(3*3)+(2*4)+(1*0)=127
127 % 10 = 7
So 80663-40-7 is a valid CAS Registry Number.

Photochemistry of 1,2-Distyrylbenzene Derivatives
Brouw, Paul M. op den,Laarhoven, Wim H.
, p. 1546 - 1555 (2007/10/02)
Photodimerization, accompanied by intramolecular, head to head cycloaddition, which is observed with unsubstituted 1,2-distyrylbenzene (12), does not occur with derivatives containing an α or β substituent. α-Substituted 1,2-distyrylbenzenes yield
