Check Digit Verification of cas no

The CAS Registry Mumber 77691-75-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,6,9 and 1 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 77691-75:
(7*7)+(6*7)+(5*6)+(4*9)+(3*1)+(2*7)+(1*5)=179
179 % 10 = 9
So 77691-75-9 is a valid CAS Registry Number.

SYNTHESIS OF 5-VINYLINDOLE

Suvorov, N. N.,Starostenko, N. E.,Zeiberlikh, F. N.

, p. 2236 - 2241 (2007/10/02)

A convenient method was developed for the synthesis of previously undescribed 5-vinylindole by catalytic dehydrogenation of 5-ethylindole.The effects of the temperature, the amount of catalyst, and the concentration of 5-ethylindole on the yield of the reaction products were investigated.The possibility of obtaining the 5-ethylindole used for dehydrogenation by heterogeneous-catalytic indolization of acetaldehyde p-ethylphenylhydrazone at aluminium oxide was investigated, and favourable conditions were found for this process.
