Check Digit Verification of cas no

The CAS Registry Mumber 1523157-59-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,2,3,1,5 and 7 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1523157-59:
(9*1)+(8*5)+(7*2)+(6*3)+(5*1)+(4*5)+(3*7)+(2*5)+(1*9)=146
146 % 10 = 6
So 1523157-59-6 is a valid CAS Registry Number.

Efficient one-pot synthesis of mono and bis-N-cyclohexyl-3-alkyl(aryl)- quinoxaline-2-amines using N-halo catalysts

Ghorbani-Vaghei, Ramin,Amiri, Mostafa,Karimi-Nami, Rahman,Salimi, Zahra

, p. 25924 - 25929 (2013/12/04)

A convenient synthetic protocol for the synthesis of mono- and bisquinoxalines involving a room temperature one-pot three-component Ugi reaction of aromatic amines, aromatic or aliphatic aldehydes and cyclohexyl isocyanide with N,N,N′,N′-tetrabromobenzene-1,3-disulfonamide [TBBDA] or poly(N-bromo-N-ethylbenzene-1,3-disulfonamide) [PBBS] as catalysts has been developed. Thin-layer chromatography was used for purification of mono and bisquinoxalines. Mild reaction conditions, good to high yields, cheap and stable catalysts and short reaction times are some of the salient features of the protocol presented.
