Check Digit Verification of cas no

The CAS Registry Mumber 66017-39-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,0,1 and 7 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 66017-39:
(7*6)+(6*6)+(5*0)+(4*1)+(3*7)+(2*3)+(1*9)=118
118 % 10 = 8
So 66017-39-8 is a valid CAS Registry Number.

A microwave-assisted synthesis of triphenodioxazines [TPDOs]

Najeebullah, Muhammad,Knight, David W.,Munawar, Munawar Ali,Yaseenx, Muhamad,Vincenzo, Fusillo

, p. 6761 - 6764 (2010)

A convenient and efficient method for the synthesis of triphenodioxazines [TPDOs] 1 by oxidative cyclisation of 2,5-bis-(arylamino)-3,6-dichlorocyclohexa- 2,5-diene-1,4-diones 6 using potassium persulfate as the oxidising agent in 9597% sulfuric acid trig

An efficient microwave assisted synthesis of triphenodioxazines using chloranil as oxidizing agent

NajeebUllah, Muhammad,Munawar, Munawar Ali,Knight, David William,Khan, Misbahul Ain,Waheed, Amran,Khan, Khalid Mohammed

, p. 318 - 325 (2016/08/20)

An efficient new method for the preparation of triphenodioxazines (TPDOs) using p-chloranil as oxidizing agent in conc. H2SO4 under microwave irradiation at 120°C is reported. This method is more efficient than the previously described microwave method using potassium persulfate as oxidising agent in conc. H2SO4 as it provides the cyclized product within 8-10 minutes with comparatively higher yields.

Microwave assisted synthesis of triphenodioxazines: A novel and convenient approach

Najeebullah, Muhammad,Munawar, Munawar Ali,Waheed, Amran,Sharif, Ahsan,Ahmed, Ejaz

experimental part, p. 671 - 675 (2012/06/18)

A novel and economical method for the synthesis of triphenodioxazines is described. The method involves the oxidative cyclisation of the intermediates 2,5-bis-(arylamino)-3,6- dichlorocyclohexa-2,5-diene-1,4-dione in 95-97% sulphuric acid under microwave
