Check Digit Verification of cas no

The CAS Registry Mumber 21272-86-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,2,7 and 2 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 21272-86:
(7*2)+(6*1)+(5*2)+(4*7)+(3*2)+(2*8)+(1*6)=86
86 % 10 = 6
So 21272-86-6 is a valid CAS Registry Number.

Pathways in the Reactions of Nitronate Ions with Sulphonyl Halides

Pigou, Paul E.,Stirling, Charles J. M.

, p. 725 - 730 (2007/10/02)

Primary and tertiary nitronate ions and sulphonyl bromides and iodides rapidly equilibrate with the nitrohalides and sulphinate ion.Products are determined by solvent and by the occurence of cross-equilibrum reactions, some of which have single-electron-transfer mechanism.The reaction of arene-sulphinate and thiolate ions with 1,2-dibromo-2-nitro-1-phenylethane gave E-β-nitrostyrene by Z-philic elimination in both cases, but the more basic thiolate ion also gave, by protophilic elimination, 2-bromo-2-nitro-1-phenylethene.
