89002-64-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89002-64-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,0,0 and 2 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 89002-64:
(7*8)+(6*9)+(5*0)+(4*0)+(3*2)+(2*6)+(1*4)=132
132 % 10 = 2
So 89002-64-2 is a valid CAS Registry Number.

Synthesis and Properties of 4H-Imidazoles
Casey, Michael,Moody, Christopher,Rees, Charles W.
, p. 1389 - 1394 (2007/10/02)
The photolysis of 1-vinyltetrazoles to give 1H-imidazoles is extended to the synthesis of isolable nonaromatic 4H-imidazoles when the vinyl group is terminally disubstituted.Thus photolysis of the 2-phenyltetrazole (7a), prepared from isobutyraldehyde, at
