1186419-79-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1186419-79-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,6,4,1 and 9 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1186419-79:
(9*1)+(8*1)+(7*8)+(6*6)+(5*4)+(4*1)+(3*9)+(2*7)+(1*9)=183
183 % 10 = 3
So 1186419-79-3 is a valid CAS Registry Number.

Iron(III) salt-catalyzed Nazarov cyclization/Michael addition of pyrrole derivatives
Fujiwara, Masamune,Kawatsura, Motoi,Hayase, Shuichi,Nanjo, Masato,Itoh, Toshiyuki
, p. 123 - 128 (2009)
The Nazarov cyclization of two types of pyrrole derivatives was effectively catalyzed by 5 mol% alumina-supported iron(III) perchlorate [Fe(ClO 4)3·Al2O3] which provided the desired cyclization with high trans s
