Check Digit Verification of cas no

The CAS Registry Mumber 192991-49-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,2,9,9 and 1 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 192991-49:
(8*1)+(7*9)+(6*2)+(5*9)+(4*9)+(3*1)+(2*4)+(1*9)=184
184 % 10 = 4
So 192991-49-4 is a valid CAS Registry Number.

Reaction of indole-2,3-dicarboxylic anhydride with grignard reagents: synthesis of 2-acylindoles

Miki, Yasuyoshi

, p. 1143 - 1150 (2007/10/03)

Reaction of indole-2,3-dicarboxylic anhydride with methylmagnesium bromide and phenylmagnesium bromide gave 2-acetyl- and 2-benzoyl-indole-3-carboxylic acids, but with tert-butylmagnesium chloride, 3-pivaloylindole-2-carboxylic acids were obtained as the main products. Treatment of 2-acylindole-3-carboxylic acids with copper chromite in quinoline or potassium hydroxide gave the corresponding 2-acylindoles.
