24503-42-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 24503-42-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,5,0 and 3 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 24503-42:
(7*2)+(6*4)+(5*5)+(4*0)+(3*3)+(2*4)+(1*2)=82
82 % 10 = 2
So 24503-42-2 is a valid CAS Registry Number.

Highly regioselective anaerobic photocyclization of 3-styrylpyridines
Lewis,Kalgutkar,Yang
, p. 3878 - 3884 (2007/10/03)
The photochemical behavior of the cis isomers of the three isomeric styrylpyridines and two (aminostyryl)pyridines has been investigated under aerobic and anaerobic conditions. Both 3-styrylpyridine and its 3′-amino derivative undergo highly regioselectiv
