Check Digit Verification of cas no

The CAS Registry Mumber 74059-27-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,0,5 and 9 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 74059-27:
(7*7)+(6*4)+(5*0)+(4*5)+(3*9)+(2*2)+(1*7)=131
131 % 10 = 1
So 74059-27-1 is a valid CAS Registry Number.

Diphenyliodonium Ion/Et3N Promoted Csp2-H Radical Phosphorylation of Enamides

Pal, Suman,Gaumont, Annie-Claude,Lakhdar, Sami,Gillaizeau, Isabelle

supporting information, p. 5621 - 5625 (2019/08/01)

This work reports a simple and efficient method for the direct phosphorylation of enamide under metal-free conditions. The P-centered radicals, derived from secondary phosphine oxides, are generated under mild reaction conditions in the presence of diphenyliodonium salt and Et3N and are introduced onto a range of enamides in good isolated yields. The method features broad substrate scope, good functional group tolerance, and efficient scale-up.

Conjugate additions of sulfur-stabilized anions to unsaturated lactams. Synthesis of polyfunctionalized benzo[a]quinolizinone systems

Garcia, Eva,Lete, Esther,Sotomayor, Nuria

, p. 6776 - 6784 (2007/10/03)

Conjugate addition reactions of sulfur-stabilized nucleophiles to the δ-lactam unit of tetrahydrobenzo[a]benzoquinolizines have been studied. The stereochemical outcome of the conjugate addition reaction depends on the nature of the substituent at the ang

Parham-type cyclization and nucleophilic addition-N-acyliminium ion cyclization sequences for the construction of the isoquinoline nucleus

Collado, M. Isabel,Sotomayor, Nuria,Villa, Maria-Jesus,Lete, Esther

, p. 6193 - 6196 (2007/10/03)

Efficient methodologies based on the nucleophilic addition-N-acyliminium ion cyclization and the Parham-type cyclization sequences of N-phenethylimides 1 and 2 are reported for the synthesis of a dibenzo[a,h]quinolizidones, thiazolo-, oxazolo-, and imidazolo[4,3-a]isoquinolones.
