89651-82-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89651-82-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,6,5 and 1 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 89651-82:
(7*8)+(6*9)+(5*6)+(4*5)+(3*1)+(2*8)+(1*2)=181
181 % 10 = 1
So 89651-82-1 is a valid CAS Registry Number.

CHEMISTRY OF 6H-PYRIDOCARBAZOLES PART II SYNTHETIC APPROACHES TO 6H-9-METHOXY-5,11-DIMETHYLPYRIDOFLUORENES
Popplestone Andrew,Sainsbury, Malcolm
, p. 4103 - 4108 (1983)
Synthetic approaches to 6H-9-methoxy-5,11-dimethylpyridofluorene are described, thus 2-6-methoxyindanone has been reacted with vinylmagnesium bromide to yield 2-(1-(4-pyridyl)ethyl)6-methoxy-1-vinyl-1-indanol.However, on dehydra
