Check Digit Verification of cas no
The CAS Registry Mumber 120834-89-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,8,3 and 4 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 120834-89:
(8*1)+(7*2)+(6*0)+(5*8)+(4*3)+(3*4)+(2*8)+(1*9)=111
111 % 10 = 1
So 120834-89-1 is a valid CAS Registry Number.

The Polonovski-Potier reaction of berbine N-oxides. Synthesis of 8-hydroxymethyl and 8-methylberbines

The Polonovski-Potier reaction of trans and cis berbines N-oxides was studied. The 8-cyano derivative obtained from trans N-oxides were used to synthesize 8-hydroxymethyl and 8-methyl berbines. This procedure was applied to the stereocontroled synthesis of (8R, 14S)-(-)-8-methylcanadine from (14S)-(-)-canadine. (C) 2000 Elsevier Science Ltd.
