Check Digit Verification of cas no

The CAS Registry Mumber 864148-39-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,4,1,4 and 8 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 864148-39:
(8*8)+(7*6)+(6*4)+(5*1)+(4*4)+(3*8)+(2*3)+(1*9)=190
190 % 10 = 0
So 864148-39-0 is a valid CAS Registry Number.

Rhodium-catalyzed asymmetric 1,6-addition of aryl zinc reagents to dienones

Hayashi, Tamio,Yamamoto, Shohei,Tokunaga, Norihito

, p. 4224 - 4227 (2005)

(Chemical Equation Presented) A highly enantioselective methodology allows the preparation of α,β-unsaturated ketones that contain a new stereogenic center at the C5 position. This approach is realized through the title reaction in the presence of chlorotrimethylsilane as a Lewis acid and a rhodium/(S)-binap complex as the catalyst followed by acidic hydrolysis (see scheme). binap = 2,2′-bis(diphenylphosphanyl)-1,1′-binaphthyl.
