Check Digit Verification of cas no

The CAS Registry Mumber 196622-28-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,6,6,2 and 2 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 196622-28:
(8*1)+(7*9)+(6*6)+(5*6)+(4*2)+(3*2)+(2*2)+(1*8)=163
163 % 10 = 3
So 196622-28-3 is a valid CAS Registry Number.

Reaction of 1-benzylindole-2,3-dicarboxylic anhydride with wittig reagents

Miki, Yasuyoshi,Hachiken, Hiroko,Sugimoto, Yoshiko,Yanase, Norihide

, p. 1759 - 1766 (2007/10/03)

Reaction of 1-benzylindole-2,3-dicarboxylic anhydride with methylene-triphenylphosphorane (Ph3P=CH2) and carbethoxymethylenetriphenylphosphorane (Ph3P=CHCOOEt) gave [2-(3-carboxyindol-2-yl)-2-oxoethylidene]triphenylphosphorane derivatives, which were converted to cyclopenta[b]indol-3-ones after decarboxylation and treatment with aldehydes. On the other hand, the anhydride reacted with carbethoxyethylidenetriphenylphosphorane (Ph3P=C(Me)COOEt) to afford a mixture of two enol lactones.
