Check Digit Verification of cas no

The CAS Registry Mumber 139261-90-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,2,6 and 1 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 139261-90:
(8*1)+(7*3)+(6*9)+(5*2)+(4*6)+(3*1)+(2*9)+(1*0)=138
138 % 10 = 8
So 139261-90-8 is a valid CAS Registry Number.

Acylation of N-p-toluenesulfonylpyrrole under Friedel-Crafts conditions: evidence for organoaluminum intermediates

Huffman, John W.,Smith, Valerie J.,Padgett, Lea W.

, p. 2104 - 2112 (2008/09/18)

The Friedel-Crafts acylation of N-p-toluenesulfonylpyrrole under Friedel-Crafts conditions has been reinvestigated. Evidence is presented in support of the hypothesis that when AlCl3 is used as the Lewis acid, acylation proceeds via reaction of
