91988-45-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91988-45-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,9,8 and 8 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 91988-45:
(7*9)+(6*1)+(5*9)+(4*8)+(3*8)+(2*4)+(1*5)=183
183 % 10 = 3
So 91988-45-3 is a valid CAS Registry Number.

Schuda, Paul Francis,Heimann, Martha R.
, p. 2365 - 2380 (2007/10/02)
The synthesis of dienone 2, which has previously been converted into the title compound in one step, is described.The methanoindene 7 is transformed into dienone-alcohol 58 in eighteen steps (12percent overall yield).This was then hydroxylated at C-8, usi
