Check Digit Verification of cas no

The CAS Registry Mumber 243128-08-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,3,1,2 and 8 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 243128-08:
(8*2)+(7*4)+(6*3)+(5*1)+(4*2)+(3*8)+(2*0)+(1*8)=107
107 % 10 = 7
So 243128-08-7 is a valid CAS Registry Number.

1,2,3,4-Tetrahydro-1-naphthyl ester as a selective protecting group for carboxylic acids

Slade, Christopher J.,Pringle, Carol A.,Sumner, Ian G.

, p. 5601 - 5604 (2007/10/03)

The carboxylic acid functionality can be protected as the 1,2,3,4- tetrahydro-1-naphthyl ester, which can be selectively cleaved in the presence of aryl and alkyl esters using chlorotrimethylsilane and sodium iodide in acetonitrile. This protecting group allows room temperature deprotection under essentially neutral conditions throughout the cleavage reaction.
