Check Digit Verification of cas no

The CAS Registry Mumber 105525-72-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,5,2 and 5 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 105525-72:
(8*1)+(7*0)+(6*5)+(5*5)+(4*2)+(3*5)+(2*7)+(1*2)=102
102 % 10 = 2
So 105525-72-2 is a valid CAS Registry Number.

Direct aromatic tert-butylation during the synthesis of thiochroman-4-ones

Clayton, Stephen E.,Gabbutt, Christopher D.,Hepworth, John D.,Mark Heron

, p. 939 - 946 (2007/10/02)

The synthesis of thiochroman-4-ones from thiophenols and 3-methylbut-2-enoic acid effected by methane sulphonic acid is accompanied by tert-butylation of the aromatic ring. 3-Arylthiobutanoic acids, available using β-butyrolactone, are efficiently cyclised in the same manner.
