Check Digit Verification of cas no

The CAS Registry Mumber 1402911-75-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,2,9,1 and 1 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1402911-75:
(9*1)+(8*4)+(7*0)+(6*2)+(5*9)+(4*1)+(3*1)+(2*7)+(1*5)=124
124 % 10 = 4
So 1402911-75-4 is a valid CAS Registry Number.

A convenient synthesis of 2-arylthiochromen-4-ones (thioflavones) by iodine-mediated cyclization of 3-aryl-1-[2-(1,1-dimethylethylsulfanyl)phenyl] prop-2-en- 1-ones

Kobayashi, Kazuhiro,Kobayashi, Akihiro,Ezaki, Kosuke

, p. 1997 - 2004 (2012/09/08)

A convenient two-step synthesis of 2-arylthiochromen-4-ones (thioflavones) beginning with 1-[2-(1,1-dimethylethylsulfanyl)phenyl]ethanones is described. Thus, 3-aryl-1-[2-(1,1-dimethylethylsulfanyl)phenyl]prop-2-en-1- ones were prepared by the condensation of 1-[2-(1,1- dimethylethylsulfanyl)phenyl] ethanones with aromatic aldehyde in the presence of sodium hydroxide, and were treated with iodine in refluxing N-methylpyrrolidin-2-one (NMP) or propanenitrile to afford the desired products in moderate to fair yields.
