Check Digit Verification of cas no

The CAS Registry Mumber 58871-04-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,8,8,7 and 1 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 58871-04:
(7*5)+(6*8)+(5*8)+(4*7)+(3*1)+(2*0)+(1*4)=158
158 % 10 = 8
So 58871-04-8 is a valid CAS Registry Number.

Lewis acid/base pair as a catalytic system for α-stereoselective synthesis of 2-deoxyglycosides through the addition of alcohols to glycals

Wang, Chen,Liang, Haijing,Hang, Zhaojun,Wang, Zhao-yan,Xie, Qinjian,Xue, Weihua

, (2020)

This report describes the α-stereoselective addition of alcohols to glycals promoted by a cooperative Lewis acid/base pair catalytic system composed of B(C6F5)3 and tetrabutylammonium bromide (TBAB), which provides access to 2-deoxylglycosides in high yields. A mechanistic investigation supported by NMR analysis highlights the possible involvement of nucleophilic addition through boron-induced activation of alcohols under the assistance of TBAB. The protocol discussed here features the high stereoselectivity, mild reaction conditions, inexpensive and stable catalysts, and a broad substrate scopes.

Asymmetric Total Synthesis of the Complex Polycyclic Xanthone FD-594

Chen, Kuanwei,Gao, Shuanhu,He, Haibing,Xie, Tao,Zheng, Chaoying

supporting information, p. 4360 - 4364 (2020/02/11)

A highly convergent approach was developed to achieve the first asymmetric and scalable total synthesis of FD-594, a complex polycyclic xanthone natural product from Streptomyces sp. TA-0256, in a longest linear sequence (LLS) of 20 steps. The trans-9,10-

Total Synthesis and Biological Evaluation of the Glycosylated Macrocyclic Antibiotic Mangrolide A

Hattori, Hiromu,Roesslein, Joel,Caspers, Patrick,Zerbe, Katja,Miyatake-Ondozabal, Hideki,Ritz, Daniel,Rueedi, Georg,Gademann, Karl

supporting information, p. 11020 - 11024 (2018/07/31)

The macrocyclic antibiotic mangrolide A has been described to exhibit potent activity against a number of clinically important Gram-negative pathogens. Reported is the first enantioselective total synthesis of mangrolide A and derivatives. Salient features of this synthesis include a highly convergent macrocycle preparation, stereoselective synthesis of the disaccharide moiety, and two β-selective glycosylations. The synthesis of mangrolide A and its analogues enabled the re-examination of its activity against bacterial pathogens, and only minimal activity was observed.
