Check Digit Verification of cas no

The CAS Registry Mumber 1498234-90-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,9,8,2,3 and 4 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1498234-90:
(9*1)+(8*4)+(7*9)+(6*8)+(5*2)+(4*3)+(3*4)+(2*9)+(1*0)=204
204 % 10 = 4
So 1498234-90-4 is a valid CAS Registry Number.

Rhodium-catalyzed direct addition of aryl C-H bonds to nitrosobenzenes at room temperature

Zhou, Bing,Du, Juanjuan,Yang, Yaxi,Feng, Huijin,Li, Yuanchao

supporting information, p. 6302 - 6305 (2014/01/17)

An unprecedented Rh-catalyzed direct addition of aryl C-H bonds to nitrosobenzenes has been developed under very mild reaction conditions (room temperature). The reaction is highly step-, atom-, and redox-economic and compatible with air and water to N-selectively provide a variety of N-diarylhydroxylamines in good to excellent yields. More importantly, this process may provide a new direction for C-N bond formation through direct C(sp2)-H functionalization.
