Check Digit Verification of cas no
The CAS Registry Mumber 21160-07-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,1,6 and 0 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 21160-07:
(7*2)+(6*1)+(5*1)+(4*6)+(3*0)+(2*0)+(1*7)=56
56 % 10 = 6
So 21160-07-6 is a valid CAS Registry Number.

N-substituted imines by the copper-catalyzed N-imination of boronic acids and organostannanes with O-acyl ketoximes
Liu, Songbai,Yu, Ying,Liebeskind, Lanny S.
, p. 1947 - 1950 (2008/02/02)
Catalytic quantities of copper(I) or copper(II) sources catalyze the N-imination of boronic acids and organostannanes through reaction with oxime O-carboxylates under nonbasic conditions. This method tolerates various functional groups and takes place efficiently using aryl, heteroaryl, and alkenyl boronic acids and stannanes.
Laser flash photolysis of carbamates derived from 9-fluorenone oxime
Bucher, G?tz,Scaiano,Sinta,Barclay,Cameron
, p. 3848 - 3855 (2007/10/02)
The photochemistry of carbamates derived from 9-fluorenone oxime was investigated by laser flash photolysis and by product studies. Primary photocleavage of the excited carbamates leads to decarboxylation and concomitant generation of the 9-fluorenone ketimine-N-yl radical and an amino radical. In the case of 9-fluorenylideneamino N-(2,5-dimethoxyphenyl)carbamate the presence of 1,4-dimethoxybenzene in the product mixture as well as spectroscopic and kinetic evidence points to the intermediary formation of triplet (2,5-dimethoxyphenyl)nitrene, which in acetonitrile dimerizes to the corresponding azo compound. Analogously, the formation of trans-azobenzene upon photolysis of 9-fluorenylideneamino N-phenylcarbamate indicates the intermediacy of parent triplet phenylnitrene, which, until now, had not been observed in solution at ambient temperature.
