1613-81-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1613-81-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,1 and 3 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1613-81:
(6*1)+(5*6)+(4*1)+(3*3)+(2*8)+(1*1)=66
66 % 10 = 6
So 1613-81-6 is a valid CAS Registry Number.

Rhodium(iii)-catalyzed formal oxidative [4 + 1] cycloaddition of benzohydroxamic acids and α-diazoesters. A facile synthesis of functionalized benzolactams

Lam, Hon-Wah,Man, Ka-Yi,Chan, Wai-Wing,Zhou, Zhongyuan,Yu, Wing-Yiu

, p. 4112 - 4116 (2014/06/10)

A Rh(iii)-catalyzed oxidative [4 + 1] cycloaddition of benzohydroxamic acids and α-diazoesters is achieved to afford benzolactams in up to 93% yields. With the N-OAc amido moiety as a directing group, the ortho-C-H is selectively functionalized and the catalytic reaction exhibits excellent tolerance to different functional substituents. A notable rhodacyclic complex is isolated and structurally characterized, suggesting that C-H/N-H cyclometallation is a key step in the catalytic cycle.

N-amidation by copper-mediated cross-coupling of organostannanes or boronic acids with O-acetyl hydroxamic acids

Zhang, Zhihui,Yu, Ying,Liebeskind, Lanny S.

supporting information; experimental part, p. 3005 - 3008 (2009/04/18)

(Chemical Equation Presented) A general nonoxidative N-amidation of organostannanes and boronic acids has been developed. Under nonbasic conditions a wide variety of aryl, alkenyl, and heteroaryl organostannanes and boronic acids couple efficiently with O-acetyl hydroxamic acids in the presence of Cu(I) sources.
