Check Digit Verification of cas no

The CAS Registry Mumber 78266-69-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,2,6 and 6 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 78266-69:
(7*7)+(6*8)+(5*2)+(4*6)+(3*6)+(2*6)+(1*9)=170
170 % 10 = 0
So 78266-69-0 is a valid CAS Registry Number.

Novel Alumina-catalysed Reactions of Arylthioalkyl Halides and Related Compounds

Jigajinni, Veerappa B.,Wightman, Richard H.

, p. 1801 - 1812 (2007/10/02)

Arylthioalkyl halides of the type ArS(CH2)nCl (Ar = phenyl or substituted phenyl, n = 1-4) undergo rearrangement on heating with neutral alumina to 1,n-bis(arylthio)alkanes of type ArS(CH2)nSAr in high yield.Similar rearrangements occur with some closely related structural types.The bis(arylthio)alkanes undergo further reaction with alumina at higher temperatures in air giving diaryl disulphides.Bis(o-iodophenylthio)methane eliminates iodine on heating with alumina, producing dibenzodithiepin.Some observations concerning the mechanism are presented.
