Check Digit Verification of cas no

The CAS Registry Mumber 143490-30-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,4,9 and 0 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 143490-30:
(8*1)+(7*4)+(6*3)+(5*4)+(4*9)+(3*0)+(2*3)+(1*0)=116
116 % 10 = 6
So 143490-30-6 is a valid CAS Registry Number.

A Facile Synthesis of Trifluoromethylamines by Oxidative Desulfurization-Fluorination of Dithiocarbamates

Kanie, Kiyoshi,Mizuno, Katsuya,Kuroboshi, Manabu,Hiyama, Tamejiro

, p. 1973 - 1991 (2007/10/03)

Trifluoromethylamines are easily synthesized from dithiocarbamates by a reagent system consisting of tetrabutylammonium dihydrogentrifluoride and an N-halo imide under mild conditions. When this reaction was applied to dithiocarbamates ArN(R)CS2Me at higher temperatures, the trifluoromethylation was accompanied by halogen substitution at the p-position of the Ar group. The synthesis of trifluoromethyl-substituted adenosine is also described.
