Check Digit Verification of cas no

The CAS Registry Mumber 120982-07-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,9,8 and 2 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 120982-07:
(8*1)+(7*2)+(6*0)+(5*9)+(4*8)+(3*2)+(2*0)+(1*7)=112
112 % 10 = 2
So 120982-07-2 is a valid CAS Registry Number.

CONVENIENT SYNTHESIS OF CROWN ETHERS CONTAINING A HYDRAZINE MOIETY

Bradshaw, Jerald S.,Krakowiak, Krzysztof E.,Wu, Geng,Izatt, Reed M.

, p. 5589 - 5592 (1988)

A new class of crown ethers containing a hydrazine moiety was synthesized in only 2, 3, or 4 steps starting from 1,2-diacetylhydrazine or 1,2-diethylhydrazine.Hydrazino-crown ethers with 2 or 4 nitrogen atoms in the ring were obtained by reacting the hydrazine derivatives with 1,11-diiodo-(or dichloro)-3,6,9-trioxaundecane, 4-allyloxymethyl-1,8-diiodo-3,6-dioxaoctane, 3-chloro-2-chloromethyl-1-propene, 1,10-dibenzyl-1,10-diaza-3,7-dioxadecane or diglycolyl dichloride (followed by reduction).The diazahydrazino-19-crown-6 compound formed a complex with methylammonium chloride.
