Check Digit Verification of cas no

The CAS Registry Mumber 1374986-89-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,4,9,8 and 6 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1374986-89:
(9*1)+(8*3)+(7*7)+(6*4)+(5*9)+(4*8)+(3*6)+(2*8)+(1*9)=226
226 % 10 = 6
So 1374986-89-6 is a valid CAS Registry Number.

An unexpected synthesis of dihydrophenazines en route to benzimidazolium salts

Borguet, Yannick,Zaragoza, Guillermo,Demonceau, Albert,Delaude, Lionel

supporting information; experimental part, p. 1356 - 1362 (2012/06/30)

The oxidation of various N,N'-diarylbenzene-1,2-diamines bearing bulky aromatic substituents with sodium periodate on wet silica gel afforded a series of five new dihydrophenazines instead of the expected cyclohexadiene-1,2- diimines. The reaction most likely proceeds via a 1,6-electrocyclic path and provides a convenient access to an important class of nitrogen heterocycles. Subsequent treatment of the mesityl derivative with chloromethyl pivalate and silver triflate led to the corresponding benzimidazolium salt. Copyright
