Check Digit Verification of cas no

The CAS Registry Mumber 128592-58-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,5,9 and 2 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 128592-58:
(8*1)+(7*2)+(6*8)+(5*5)+(4*9)+(3*2)+(2*5)+(1*8)=155
155 % 10 = 5
So 128592-58-5 is a valid CAS Registry Number.

Diastereoselective addition of organometallic reagents to chiral iminium ions: Synthesis of (S)-(+)-cryptostyline I

Polniaszek, Richard P.,Dillard, Lawrence W.

, p. 797 - 800 (2007/10/02)

Iminium ion 2c participates in stereoselective nucleophilic addition reactions with Grignard reagents. Analysis of the products from reaction of 5-hexenylmagnesium bromide with iminium ion 2a suggests that these reactions proceed by a polar (two electron) mechanism. The utility of this chemistry is demonstrated in a stereo specific synthesis of (5)-(+)-cryptostylina I.
