Check Digit Verification of cas no
The CAS Registry Mumber 1166995-02-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,6,6,9,9 and 5 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1166995-02:
(9*1)+(8*1)+(7*6)+(6*6)+(5*9)+(4*9)+(3*5)+(2*0)+(1*2)=193
193 % 10 = 3
So 1166995-02-3 is a valid CAS Registry Number.

Oxidation of 2,5-dialkylpyrrole derivatives with cerium(IV) ammonium nitrate
Voloshchuk, Roman,Galezowski, Michal,Gryko, Daniel T.
, p. 1147 - 1152 (2009)
A new four-step procedure for the synthesis of 2,5-diformylpyrrole from hexane-2,5-dione was developed. The oxidation reaction of substituted 2,5-dialkylpyrroles with cerium(IV) ammonium nitrate (CAN) has been studied in detail. It was found that the outc
