852248-60-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 852248-60-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,2,2,4 and 8 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 852248-60:
(8*8)+(7*5)+(6*2)+(5*2)+(4*4)+(3*8)+(2*6)+(1*0)=173
173 % 10 = 3
So 852248-60-3 is a valid CAS Registry Number.

Synthesis of the AC ring of paclitaxel: Formation of the C ring by [3+2] cycloaddition with a preformed A ring

Nakai, Kazuoki,Doi, Takayuki,Takahashi, Takashi

, p. 866 - 868 (2007/10/03)

The stereoselective formation of the C ring was accomplished by nitrile oxide [3+2] cycloaddition of an intermediate with the A ring already constructed. We found that stereoelectronic effect to a 1,1-substituted alkene moiety is important in the reaction
