80663-47-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80663-47-4 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 7 respectively.
Calculate Digit Verification of CAS Registry Number 80663-47:
(7*8)+(6*0)+(5*6)+(4*6)+(3*3)+(2*4)+(1*7)=134
134 % 10 = 4
So 80663-47-4 is a valid CAS Registry Number.

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
