Check Digit Verification of cas no

The CAS Registry Mumber 170309-07-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,0,3,0 and 9 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 170309-07:
(8*1)+(7*7)+(6*0)+(5*3)+(4*0)+(3*9)+(2*0)+(1*7)=106
106 % 10 = 6
So 170309-07-6 is a valid CAS Registry Number.

Synthese et Reactions SRN1 en Serie 3-Nitroimidazopyrimidine

Roubaud, Christine,Vanelle, Patrice,Maldonado, Jose,Crozet, Michel P.

, p. 9643 - 9656 (1995)

A new heterocyclic reductive alkylating agent, 2-chloromethyl-3-nitroimidazopyrimidine, is synthesized for the first time and shown to react under phase-transfer catalysis conditions with 2-nitropropane anion to give good yield of the C-alkylated derivative.Elimination of nitrous acid allows to obtain a new class of imidazopyrimidine derivatives bearing a trisubstituted ethylenic bond in the 2 position.The SRN1 mechanism of C-alkylation is confirmed by classical inhibition experiments by dioxygen, p-dinitrobenzene or TEMPO.
