185376-75-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 185376-75-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,5,3,7 and 6 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 185376-75:
(8*1)+(7*8)+(6*5)+(5*3)+(4*7)+(3*6)+(2*7)+(1*5)=174
174 % 10 = 4
So 185376-75-4 is a valid CAS Registry Number.

Asymmetric Hydrogenation of β-Secondary Amino Ketones Catalyzed by a Ruthenocenyl Phosphino-oxazoline-ruthenium Complex (RuPHOX-Ru): The Synthesis of γ-Secondary Amino Alcohols

Wang, Jianxia,Wang, Yanzhao,Liu, Delong,Zhang, Wanbin

, p. 3262 - 3272 (2015/11/03)

A ruthenocenyl phosphino-oxazoline-ruthenium complex (RuPHOX-Ru) was applied successfully to the asymmetric hydrogenation of β-secondary amino ketones, directly affording the corresponding chiral γ-secondary amino alcohols in up to 99% yield and with 99% ee. Reaction with β-(benzylamino)-1-phenylpropan-1-one could be performed on a gram-scale with a relatively low catalyst loading (up to 2000 S/C). The resulting hydrogenated product could be used for the synthesis of synthetically useful compounds.
