220626-57-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 220626-57-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,6,2 and 6 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 220626-57:
(8*2)+(7*2)+(6*0)+(5*6)+(4*2)+(3*6)+(2*5)+(1*7)=103
103 % 10 = 3
So 220626-57-3 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.
