Check Digit Verification of cas no
The CAS Registry Mumber 89331-01-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,3,3 and 1 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 89331-01:
(7*8)+(6*9)+(5*3)+(4*3)+(3*1)+(2*0)+(1*1)=141
141 % 10 = 1
So 89331-01-1 is a valid CAS Registry Number.

BENZINDOLES - I. THE USE OF TERT-BUTOXY-BIS(DIMETHYLAMINO)METHANE AS CONDENSATION REAGENT.
Haefliger, W.,Knecht, H.
, p. 285 - 288 (2007/10/02)
A simple and efficient route to benzindoles is the reaction of nitrotetralins with Bredereck's reagent and reduction of the condensation product to the corresponding annelated indole.
