Check Digit Verification of cas no

The CAS Registry Mumber 540518-83-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,4,0,5,1 and 8 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 540518-83:
(8*5)+(7*4)+(6*0)+(5*5)+(4*1)+(3*8)+(2*8)+(1*3)=140
140 % 10 = 0
So 540518-83-0 is a valid CAS Registry Number.

Iridium-catalyzed direct arene C-H bond amidation with sulfonyl- and aryl azides

Lee, Donggun,Kim, Youngchan,Chang, Sukbok

, p. 11102 - 11109 (2013)

Iridium-catalyzed direct ortho C-H amidation of arenes has been shown to work well with sulfonyl- and aryl azides as the nitrogen source. The reaction proceeds efficiently with a broad range of substrates bearing conventional directing groups with excellent functional group compatibility under mild conditions. In addition, substrates forming not only 5- but also 6-membered iridacycle intermediates undergo the C-H amidation with high selectivity.
