Check Digit Verification of cas no

The CAS Registry Mumber 213190-13-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,3,1,9 and 0 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 213190-13:
(8*2)+(7*1)+(6*3)+(5*1)+(4*9)+(3*0)+(2*1)+(1*3)=87
87 % 10 = 7
So 213190-13-7 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.
