Check Digit Verification of cas no

The CAS Registry Mumber 83585-63-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,5,8 and 5 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 83585-63:
(7*8)+(6*3)+(5*5)+(4*8)+(3*5)+(2*6)+(1*3)=161
161 % 10 = 1
So 83585-63-1 is a valid CAS Registry Number.

Facile Synthesis of Monoaza Crown Ethers

Maeda, Hirokazu,Nakatsuji, Yohji,Okahara, Mitsuo

, p. 471 - 472 (1981)

A facile one-step synthesis of monoaza crown ethers by treatment of dialkanolamines with oligoethylene glycol di(toluene-p-sulphonates) or dichlorides in ButOM-ButOH (M = Na, K) is described.

Synthesis of Aminomethyl Crown Ethers

Maeda, Hirokazu,Kikui, Takashi,Nakatsuji, Yohji,Okahara, Mitsuo

, p. 5167 - 5171 (2007/10/02)

Various N-substituted or unsubstituted aminomethyl crown ethers, which possess a reactive amino group, were prepared in good yields by the reaction between 3-amino-1,2-propanediols or aminomethyl oligoethylene glycols and oligoethylene glycol ditosylates or dichlorides.The scope of the reaction was investigated and the complexing ability of these new crown ether derivatives with sodium and potassium ions in methanol was measured by potentiometric titration.
