120998-91-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 120998-91-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,9,9 and 8 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 120998-91:
(8*1)+(7*2)+(6*0)+(5*9)+(4*9)+(3*8)+(2*9)+(1*1)=146
146 % 10 = 6
So 120998-91-6 is a valid CAS Registry Number.

Camps, P.,Jaime, C.
, p. 393 - 396 (1980)
Several 2,4-dialkoxybicyclooctan-8-ones have been prepared as mixtures of stereoisomers which could be separated and characterised by 60 MHz 1H NMR spectroscopy using Eu(FOD)3
