Check Digit Verification of cas no

The CAS Registry Mumber 4073-98-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,0,7 and 3 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 4073-98:
(6*4)+(5*0)+(4*7)+(3*3)+(2*9)+(1*8)=87
87 % 10 = 7
So 4073-98-7 is a valid CAS Registry Number.

Highly regioselective para-methylthiolation/bridging methylenation of arylamines promoted by NH4I

Xu, Yinfeng,Cong, Tiantian,Liu, Ping,Sun, Peipei

supporting information, p. 9742 - 9745 (2015/10/05)

Aryl methyl thioethers and methylene-bridged arylamines were synthesized via highly regioselective para-methylthiolation/bridging methylenation of arylamines using DMSO as the methylthio or methylene source in the presence of NH4I under metal-free conditions. For the substrates with both electron-donating and electron-withdrawing substituents, the reaction proceeded smoothly and gave moderate to good yields.

Novel anilines of the 2,6-dialkyl-4-dialkylaminomethylaniline type are prepared by reacting a secondary amine and an aldehyde with a primary aniline reactant having a free para position and substituents in both ortho positions in the presence of an acid catalyst, the amounts of amine and acid employed being at least equimolar with respect to the amount of aldehyde, and the reaction being conducted by adding the primary aniline reactant to a preformed mixture of the secondary amine, aldehyde, and acid.
