Check Digit Verification of cas no

The CAS Registry Mumber 64388-26-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,3,8 and 8 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 64388-26:
(7*6)+(6*4)+(5*3)+(4*8)+(3*8)+(2*2)+(1*6)=147
147 % 10 = 7
So 64388-26-7 is a valid CAS Registry Number.

CuI-catalyzed coupling of gem-dibromovinylanilides and sulfonamides: An efficient method for the synthesis of 2-amidoindoles and indolo[1,2-a] quinazolines

Kiruthika, Selvarangam E.,Perumal, Paramasivan Thirumalai

, p. 484 - 487 (2014/04/03)

A Cu(I)-catalyzed, intermolecular protocol for the synthesis of 2-amidoindoles and tetrahydroindolo[1,2-a]quinazolines in shorter time and high yields is reported. The key highlight of this disclosure is the formation of 2-amidoindole and tetrahydroindolo[1,2-a]quinazoline moieties directly from gem-dibromovinylanilides and sulfonamides in a one-pot fashion through the in situ formation of ynamides followed by a base-promoted intramolecular hydroamidation.
