Check Digit Verification of cas no

The CAS Registry Mumber 1190880-23-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,0,8,8 and 0 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1190880-23:
(9*1)+(8*1)+(7*9)+(6*0)+(5*8)+(4*8)+(3*0)+(2*2)+(1*3)=159
159 % 10 = 9
So 1190880-23-9 is a valid CAS Registry Number.

Regioselective arylations of α-amido sulfones with electron-rich arenes through friedel-crafts alkylations catalyzed by ferric chloride hexahydrate: Synthesis of unsymmetrical and bis-symmetrical triarylmethanes

Thirupathi, Ponnaboina,Kim, Sung Soo

experimental part, p. 1798 - 1808 (2010/06/15)

Ferric chloride hexahydrate is a highly efficient catalyst for the regioselective arylation of α-amido sulfones. The products undergo further Friedel-Crafts alkylations with heteroaromatic or electron-rich arenes to afford unsymmetrical or bis-symmetrical
