Check Digit Verification of cas no

The CAS Registry Mumber 80595-17-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,5,9 and 5 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 80595-17:
(7*8)+(6*0)+(5*5)+(4*9)+(3*5)+(2*1)+(1*7)=141
141 % 10 = 1
So 80595-17-1 is a valid CAS Registry Number.

Preparation of Chiral Diphenyl-Substituted Polyether-Diester Compounds

Bradshaw, Jerald S.,Jolley, Scott T.,Izatt, Reed M.

, p. 1229 - 1232 (2007/10/02)

A new series of chiral polyether-diester ligands has been prepared by reacting racemic and chiral diphenyl-substituted tetraethylene glycols with diglycolyl chloride (5 and 6), 2,5-furandicarbonyl chloride (7 and 8), 2,6-pyridinedicarbonyl chloride (9-12), and 4-methoxy-2,6-pyridinedicarbonyl chloride (13).The chiral diphenyl-substituted tetraethylene glycols were prepared from the dl-, (S)-, and (R)-mandelic acids.
