Check Digit Verification of cas no

The CAS Registry Mumber 136944-01-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,9,4 and 4 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 136944-01:
(8*1)+(7*3)+(6*6)+(5*9)+(4*4)+(3*4)+(2*0)+(1*1)=139
139 % 10 = 9
So 136944-01-9 is a valid CAS Registry Number.

Synthesis of unsymmetrically substituted benzils via the Friedel-Crafts reaction of arenes with α-chloro-α-(methylthio)acetophenones

Ishibashi,Matsuoka,Ikeda

, p. 1854 - 1856 (1991)

Lewis acid-promoted reactions of arenes with α-chloro-α-(methylthio)acetophenones gave the Friedel-Crafts reaction products, which were then treated with 3 molar eq of cupric chloride in aqueous acetone to afford the unsymmetrically substituted benzils.
