Check Digit Verification of cas no

The CAS Registry Mumber 1189747-13-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,9,7,4 and 7 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1189747-13:
(9*1)+(8*1)+(7*8)+(6*9)+(5*7)+(4*4)+(3*7)+(2*1)+(1*3)=204
204 % 10 = 4
So 1189747-13-4 is a valid CAS Registry Number.

Synthesis of 3-acetoxyacetanilide derivatives by means of semmler-wolff-type aromatization reaction of cyclohexane-1,3-dione monooximes

Ishikawa, Teruhiko,Arai, Masaki,Nishiuchi, Hironori,Ishiguro, Hiroshi,Saito, Seiki

supporting information; experimental part, p. 1066 - 1067 (2009/12/02)

A novel method for synthesizing 3-acetoxyaniline derivatives from substituted cyclohexane-l, 3-diones is described. This synthetic process includes regioselective formation of cyclohexane-l, 3-dione monooximes 2 and their Semmler-Wolff-type aromatization under very simple reaction conditions. Copyright
