1158819-60-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1158819-60-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,5,8,8,1 and 9 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1158819-60:
(9*1)+(8*1)+(7*5)+(6*8)+(5*8)+(4*1)+(3*9)+(2*6)+(1*0)=183
183 % 10 = 3
So 1158819-60-3 is a valid CAS Registry Number.

Partially saturated indeno[1,2-b]indole derivatives via deoxygenation of heterocyclic α-hydroxy-N,O-hemiaminals
Hemmerling, Hans-Joerg,Reiss, Guido
experimental part, p. 985 - 999 (2009/12/01)
A series of 3-aminocyclohex-2-enones were reacted with indane-1,2,3-trione monohydrate (ninhydrin) yielding 4b,9b-dihydroxyindeno[ 1,2-b]indoles that were deoxygenated to indeno[1,2-b]indoles. Georg Thieme Verlag Stuttgart.
