Check Digit Verification of cas no

The CAS Registry Mumber 18159-25-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,1,5 and 9 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 18159-25:
(7*1)+(6*8)+(5*1)+(4*5)+(3*9)+(2*2)+(1*5)=116
116 % 10 = 6
So 18159-25-6 is a valid CAS Registry Number.

Sulfur-based protecting groups for pyrroles and the facile deprotection of 2-(2,4-dinitrobenzene)sulfinyl and sulfonyl pyrroles

Thompson, Alison,Butler, R. Jonathan,Grundy, Meaghan N.,Laltoo, Andrea B. E.,Robertson, Katherine N.,Cameron, T. Stanley

, p. 3753 - 3756 (2005)

(Chemical Equation Presented) The effectiveness of simple sulfinyl and sulfonyl groups as electron-withdrawing protecting groups for pyrroles has been analyzed using 13C NMR spectroscopy and confirmed by consideration of X-ray crystal structures. Additionally, the 2,4-dinitrobenzenesulfinyl and sulfonyl groups are shown to be effective electron-withdrawing protecting groups for pyrroles, and they can be removed by treatment with benzene thiol or thiolate under mild and specific conditions.
