Check Digit Verification of cas no

The CAS Registry Mumber 796042-64-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,9,6,0,4 and 2 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 796042-64:
(8*7)+(7*9)+(6*6)+(5*0)+(4*4)+(3*2)+(2*6)+(1*4)=193
193 % 10 = 3
So 796042-64-3 is a valid CAS Registry Number.

A new class of substituted aryl bis(oxazoline) ligands for highly enantioselective copper-catalyzed asymmetric aldol addition of dienolsilane to pyruvate and glyoxylate esters

Le, Julie Cong-Dung,Pagenkopf, Brian L.

, p. 4097 - 4099 (2007/10/03)

(Chemical Equation Presented) A new class of bis(oxazoline) ligands are introduced that feature o-alkoxyaryl substituents and provide the highest enantioselectivities yet reported for the copper-catalyzed asymmetric dienosilane aldol addition to pyruvate and glyoxylate esters. Enantioselectivities up to 98% ee (before recrystallization) and isolated yields up to 91% were observed. Additionally, chloride counterions were found to be superior to triflate for this reaction.
