194989-04-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 194989-04-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,4,9,8 and 9 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 194989-04:
(8*1)+(7*9)+(6*4)+(5*9)+(4*8)+(3*9)+(2*0)+(1*4)=203
203 % 10 = 3
So 194989-04-3 is a valid CAS Registry Number.

Synthesis of pyrrolizidines by cascade reactions of N- alkenylaziridinylmethyl radicals
De Smaele, Dirk,Bogaert, Piet,De Kimpe, Norbert
, p. 9797 - 9800 (2007/10/03)
Pyrrolizidines were synthesized in a one-step-reaction from 2- (bromomethyl)aziridines via a cascade of radical reactions involving aziridinylmethyl radicals. N-allylaminyl radicals and carbon-centered pyrrolidinyl radicals.
