119969-33-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 119969-33-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,9,6 and 9 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 119969-33:
(8*1)+(7*1)+(6*9)+(5*9)+(4*6)+(3*9)+(2*3)+(1*3)=174
174 % 10 = 4
So 119969-33-4 is a valid CAS Registry Number.

Enantioselective ring-opening reactions of racemic ethynyl epoxides via copper-allenylidene intermediates: Efficient approach to chiral β-amino alcohols

Hattori, Gaku,Yoshida, Akiko,Miyake, Yoshihiro,Nishibayashi, Yoshiaki

experimental part, p. 7603 - 7607 (2009/12/24)

(Chemical Equation Presented) Enantioselective copper-catalyzed ring-opening reactions of racemic ethynyl epoxides with amines using (R)-DTBM-MeO-BIPHEP as a chiral ligand have been found to give the corresponding amino alcohols in high yields with up to
