Check Digit Verification of cas no
The CAS Registry Mumber 122947-08-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,9,4 and 7 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 122947-08:
(8*1)+(7*2)+(6*2)+(5*9)+(4*4)+(3*7)+(2*0)+(1*8)=124
124 % 10 = 4
So 122947-08-4 is a valid CAS Registry Number.

A SIMPLE SYNTHESIS OF 2-VINILINDOLES
Macor, John E.,Newman, Michael E.,Ryan, Kevin
, p. 2509 - 2512 (1989)
A two step synthesis of 2-vinyl indoles is described.Reaction of the anions of 2-methylindole-3-carboxylates (1) and (5) with ketones and aldehydes leads directly to 2-vinylindole-3-carboxylic acids (3) and esters (7), respectively.Decarboxylation of the acids (3) yields the desired 2-vinylindoles (4).
