The CAS Registry Mumber 154349-34-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,4,3,4 and 9 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 154349-34:
(8*1)+(7*5)+(6*4)+(5*3)+(4*4)+(3*9)+(2*3)+(1*4)=135
135 % 10 = 5
So 154349-34-5 is a valid CAS Registry Number.

A Facile Entry to Macrocyclic Disulfides: An Efficient Synthesis of Redox-Switched Crown Ethers

Ramesha, A. R.,Chandrasekaran, Srinivasan

, p. 1354 - 1357 (1994)

An interesting sulfur transfer reaction with benzyltriethylammonium tetrathiomolybdate has been used efficiently for the synthesis of macrocyclic disulfides.This methodology has been extended to a high-yield synthesis of "redox-switched" crown ethers which have potential application for selective ion transport across liquid membranes.
