Check Digit Verification of cas no

The CAS Registry Mumber 228703-72-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,8,7,0 and 3 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 228703-72:
(8*2)+(7*2)+(6*8)+(5*7)+(4*0)+(3*3)+(2*7)+(1*2)=138
138 % 10 = 8
So 228703-72-8 is a valid CAS Registry Number.

Secondary Aminophosphanes - Synthesis and Reactivity

Niecke, Edgar,Rueger, Reinhold,Gueth, Werner

, p. 1049 - 1052 (2007/10/02)

Secondary diaminophosphanes 1c-e as well as alkylaminophosphanes 1g, h are available by the reaction of the corresponding chlorophosphanes with lithium-tetrahydridoaluminate.With triethylamine containing three equivalents of hydrogen fluoride, the aminophosphanes 1d, g are converted into the secondary fluorophosphanes 2a, b.While 1c-e are thermally quite stable, 1f-h and 2a, b decompose to give diphosphanes through elimination of amine and hydrogen fluoride. - Key words: Secondary Aminophosphanes, Decomposition, Substitution, Reactions with HF
