Check Digit Verification of cas no

The CAS Registry Mumber 1404220-27-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,4,2,2 and 0 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1404220-27:
(9*1)+(8*4)+(7*0)+(6*4)+(5*2)+(4*2)+(3*0)+(2*2)+(1*7)=94
94 % 10 = 4
So 1404220-27-4 is a valid CAS Registry Number.

Rhodium-catalyzed direct C-H amination of benzamides with aryl azides: A synthetic route to diarylamines

Ryu, Jaeyune,Shin, Kwangmin,Park, Sae Hume,Kim, Ji Young,Chang, Sukbok

, p. 9904 - 9908 (2012/10/29)

No muss, no fuss: A rhodium-catalyzed direct intermolecular C-H amination of benzamides and ketoximes using aryl azides as the amine source has been developed. The reaction exhibits a broad substrate scope with excellent functional-group tolerance, requires no external oxidants, releases N 2 as the only by-product, and produces diarylamines in high yields.
