221247-76-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 221247-76-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,1,2,4 and 7 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 221247-76:
(8*2)+(7*2)+(6*1)+(5*2)+(4*4)+(3*7)+(2*7)+(1*6)=103
103 % 10 = 3
So 221247-76-3 is a valid CAS Registry Number.

Asymmetric synthesis of 2-arylpyrrolidines by cationic cyclization
Coldham, Iain,Robinson, Steven P.,Baxter, Carl A.
, p. 2405 - 2407 (2013/07/11)
Homoallylic amines were prepared by asymmetric deprotonation of benzylamines using n-BuLi and (-)-sparteine to give chiral organolithiums to which were added prenyl bromide. Removal of the Boc protecting group gave anilines that were found to undergo Br?n
