Check Digit Verification of cas no

The CAS Registry Mumber 1440935-20-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,0,9,3 and 5 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1440935-20:
(9*1)+(8*4)+(7*4)+(6*0)+(5*9)+(4*3)+(3*5)+(2*2)+(1*0)=145
145 % 10 = 5
So 1440935-20-5 is a valid CAS Registry Number.

Efficient synthesis and structure peculiarity of macrocycles with bi-indolizinylquinoxalinone moieties

Mamedov, Vakhid A.,Kalinin, Aleksey A.,Gubaidullin, Aidar T.,Katsuba, Sergey A.,Syakaev, Victor V.,Rizvanov, Il'Dar K.,Latypov, Shamil K.

, p. 10675 - 10687 (2013)

Monoindolizinylquinoxalinepodands, easily available from indolizinylquinoxalines and various dihalides, undergo smooth oxidative dimerization in the presence of molecular iodine to afford corresponding macrocycles in good yields in a short reaction time.

Iodine-sodium acetate (I2-NaOAc) mediated oxidative dimerization of indolizines: An efficient method for the synthesis of biindolizines

Mamedov, Vakhid A.,Kalinin, Aleksey A.,Samigullina, Aida I.,Mironova, Ekaterina V.,Krivolapov, Dimitry B.,Gubaidullin, Aidar T.,Rizvanov, Il'Dar K.

, p. 3348 - 3352 (2013/07/05)

An I2-NaOAc mediated one-pot process for the oxidative dimerization of indolizines under mild conditions is described. The reaction afforded a variety of products in good to excellent yields from indolizines with acceptor groups. Macrocyclic sy
