120343-76-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 120343-76-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,3,4 and 3 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 120343-76:
(8*1)+(7*2)+(6*0)+(5*3)+(4*4)+(3*3)+(2*7)+(1*6)=82
82 % 10 = 2
So 120343-76-2 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.
