101220-38-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 101220-38-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,1,2,2 and 0 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 101220-38:
(8*1)+(7*0)+(6*1)+(5*2)+(4*2)+(3*0)+(2*3)+(1*8)=46
46 % 10 = 6
So 101220-38-6 is a valid CAS Registry Number.

One-pot highly diastereoselective annulation to N-unprotected tetrasubstituted 2-pyrrolines

Meninno, Sara,Capobianco, Amedeo,Peluso, Andrea,Lattanzi, Alessandra

supporting information, p. 2137 - 2140 (2015/04/27)

A one-pot DABCO-catalysed Michael addition of glycine imine-derived esters to trans-2-aroyl-3-arylacrylonitriles followed by a deprotection/cyclization/tautomerization sequence afforded tetrasubstituted N-unprotected trans-2-pyrrolines in up to 96% yield.

Microwave synthesis of α-cyano chalcones

Deshpande, Shyam J.,Leger, Paul R.,Sieck, Stephen R.

supporting information; experimental part, p. 1772 - 1775 (2012/05/04)

A novel methodology for facile production of α-cyano chalcones under microwave irradiation is described. Utilizing a Knoevenagel condensation between benzoylacetonitriles and aromatic aldehydes, substituted chalcones are generated via a 15-min, one-pot synthesis. Diversification of aromatic groups, including electron-withdrawing, electron-donating, and heterocyclic substitutions, has led to the isolation of over twenty colored, solid chalcone products. Furthermore the methodology can be extended to the synthesis of benzylidenemalononitriles as well as methyl and ethyl α-cyano cinnamates.
