216590-89-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 216590-89-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,6,5,9 and 0 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 216590-89:
(8*2)+(7*1)+(6*6)+(5*5)+(4*9)+(3*0)+(2*8)+(1*9)=145
145 % 10 = 5
So 216590-89-5 is a valid CAS Registry Number.

Alkynenitriles: chelation-controlled conjugate additions

Fleming, Fraser F.,Gudipati, Venugopal,Steward, Omar W.

, p. 659 - 661 (2002)

Chelation between γ-hydroxybutynenitrile and Grignard reagents triggers a particularly facile anionic conjugate addition reaction. Structurally diverse Grignard reagents add with equal efficiency, providing an intermediate anion that stereoselectively alk

Alkynenitriles: Stereoselective chelation controlled conjugate addition-alkylations

Fleming, Fraser F.,Gudipati, Venugopal,Steward, Omar W.

, p. 5585 - 5593 (2003)

Chelation-controlled conjugate addition of Grignard reagents to γ-hydroxyalkynenitriles stereoselectively generates tri- and tetra-substituted alkenenitriles. t-BuMgCl-initiated deprotonation of hydroxyalkynenitriles followed by addition of a second Grignard reagents triggers a facile conjugate addition leading to a cyclic magnesium chelate. Protonation of the chelate stereoselectively generates trisubstituted nitriles whereas the addition of t-BuLi causes conversion to an 'ate' complex that allows alkylation with aldehyde electrophiles. The chelation-controlled conjugate addition-alkylation generates tri- and tetra-substituted alkenenitriles that are otherwise difficult to synthesize.
