58577-60-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 58577-60-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,8,5,7 and 7 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 58577-60:
(7*5)+(6*8)+(5*5)+(4*7)+(3*7)+(2*6)+(1*0)=169
169 % 10 = 9
So 58577-60-9 is a valid CAS Registry Number.

Organocatalyzed asymmetric vinylogous Michael addition of α,β-unsaturated γ-butyrolactam

Zhang, Jinlong,Liu, Xihong,Ma, Xiaojuan,Wang, Rui

supporting information, p. 9329 - 9331 (2013/10/01)

Highly efficient asymmetric vinylogous 1,6-Michael addition of α,β-unsaturated γ-butyrolactam to 3-methyl-4-nitro-5-alkenyl- isoxazoles and Michael addition to trichloromethyl ketones by using a chiral quinine-derived squaramide organocatalyst were described, giving products with high diastereo- and enantioselectivities (up to >25:1 dr and 96% ee).

Decomposition of sodium trichloroacetate in the presence of quaternary ammonium under microwave irradiation: A convenient one-pot synthesis of α-hydroxy acids in water

Yu, Haitao,Fang, Yun,Xia, Yongmei,Wu, Jing

, p. 2421 - 2426 (2007/10/03)

A good yielding phase-transfer-catalyzed procedure for one-pot preparation of α-hydroxy acids from carbonyl compounds and sodium trichloroacetate by in situ addition and hydrolysis under microwave irradiation is described. Decomposition of sodium trichloroacetate is strongly accelerated by the presence of quaternary ammonium. The reaction can be conducted in water. Copyright Taylor & Francis Group, LLC.
