Check Digit Verification of cas no

The CAS Registry Mumber 57058-22-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,0,5 and 8 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 57058-22:
(7*5)+(6*7)+(5*0)+(4*5)+(3*8)+(2*2)+(1*2)=127
127 % 10 = 7
So 57058-22-7 is a valid CAS Registry Number.

An expedient synthesis of olfactory lactones by intramolecular hydroacylalkoxylation reactions

Adrio, Luis A.,Hii, King Kuok Mimi

, p. 1852 - 1857 (2011/05/05)

A series of 4,5-disubstituted γ-lactones, including whisky and cognac lactones, was synthesised in four steps from a readily available chiral precursor. By using an intramolecular hydroacylalkoxylation reaction in the final step, a correlation between the (E)/(Z) configuration of the precursor and the product distribution has been established, for the first time, in this type of cyclisation reactions.
