120626-39-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 120626-39-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,6,2 and 6 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 120626-39:
(8*1)+(7*2)+(6*0)+(5*6)+(4*2)+(3*6)+(2*3)+(1*9)=93
93 % 10 = 3
So 120626-39-3 is a valid CAS Registry Number.

MACROHETEROCYCLES. XLIII. SYNTHESIS OF (3N+1)-CROWN-n ETHERS
Luk'yanenko, N. G.,Mel'nik, O. T.
, p. 1975 - 1983 (2007/10/02)
The condensation of substituted bispropane-1,3-diols with di-p-tosyloxy derivatives of polyethyleneglycols gave the corresponding bis-(3n+1)-crown-n ethers.The products mostly form complexes of the "sandwich" type with the cations of alkali and alkaline-earth metals.
