Check Digit Verification of cas no

The CAS Registry Mumber 1402844-74-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,2,8,4 and 4 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1402844-74:
(9*1)+(8*4)+(7*0)+(6*2)+(5*8)+(4*4)+(3*4)+(2*7)+(1*4)=139
139 % 10 = 9
So 1402844-74-9 is a valid CAS Registry Number.

Iron-catalyzed N-alkylation of azoles via cleavage of an sp3 C-H bond adjacent to a nitrogen atom

Xia, Qinqin,Chen, Wanzhi

supporting information, p. 9366 - 9373,8 (2012/12/12)

Iron-catalyzed direct C-N bond formation between azoles and amides is described. The oxidative coupling reactions of sp3 C-H bonds adjacent to a nitrogen atom in amides and sulfonamides with the N-H bond in azoles proceeded smoothly in the presence of FeCl2 and di-tert-butyl peroxide (DTBP).
