871333-32-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 871333-32-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,1,3,3 and 3 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 871333-32:
(8*8)+(7*7)+(6*1)+(5*3)+(4*3)+(3*3)+(2*3)+(1*2)=163
163 % 10 = 3
So 871333-32-3 is a valid CAS Registry Number.

Pare, Emily C.,Brook, David J. R.,Brieger, Aaron,Badik, Mick,Schinke, Marie
, p. 4258 - 4261 (2005)
1,5-Diisopropyl-6-oxo-verdazyl free radicals were synthesized via the condensation of BOC protected isopropyl hydrazine with phosgene, deprotection with aqueous HCl, condensation with aldehydes to form tetrazanes and finally oxidation to give the free rad
