Check Digit Verification of cas no

The CAS Registry Mumber 608529-29-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,0,8,5,2 and 9 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 608529-29:
(8*6)+(7*0)+(6*8)+(5*5)+(4*2)+(3*9)+(2*2)+(1*9)=169
169 % 10 = 9
So 608529-29-9 is a valid CAS Registry Number.

Lactones. Part 16: Lactonization of γ,δ-epoxy esters with p-toluenesulfonic acid monohydrate

Wawrzeńczyk, Czes?aw,Grabarczyk, Ma?gorzata,Bia?ońska, Agata,Ciunik, Zbigniew

, p. 6595 - 6601 (2003)

The reaction of cyclic γ,δ-epoxy esters with p-toluenesulfonic acid monohydrate is described. The reaction carried out in benzene or methylene chloride gave tosyloxy lactones as product. The ethoxy or methoxy lactones were obtained when ethanol or methanol were used as solvent. A mechanism of this lactonization is proposed.
