Check Digit Verification of cas no

The CAS Registry Mumber 138500-87-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,5,0 and 0 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 138500-87:
(8*1)+(7*3)+(6*8)+(5*5)+(4*0)+(3*0)+(2*8)+(1*7)=125
125 % 10 = 5
So 138500-87-5 is a valid CAS Registry Number.

Guanosine Borate Hydrogel and Self-Assembled Nanostructures Capable of Enantioselective Aldol Reaction in Water

Chen, Zhaohang,Zhou, Pengcheng,Guo, Yuanxia,Anna, None,Bai, Jiakun,Qiao, Renzhong,Li, Chao

supporting information, p. 2624 - 2631 (2022/02/16)

A guanosine-based hydrogel formed by the self-assembly of guanosine and 4-((l-prolinamide)methyl)phenylboronic acid was constructed. The G quartets were selectively stabilized by K+ ions to form a self-supporting transparent hydrogel. These guanosine-derived assemblies were used to catalyze the aldol reaction in water without any additives, affording desirable conversion and enantioselectivity of the product. The controlled assays of small-molecule components indicated that the stable assemblies were the definite species that achieved high enantioselective catalysis. The current catalytic system can be readily recovered by simple extraction and still acquired good performance of the reaction after four cycles.

Pd-Catalyzed Site-Selective Borylation of Simple Arenes via Thianthrenation?

Chen, Xiao-Yue,Huang, Yu-Hao,Zhou, Jian,Wang, Peng

, p. 1269 - 1272 (2020/08/13)

Site-selective borylation of simple arenes was realized in one pot via an electrophilic thianthrenation/Pd-catalyzed borylation sequence. The key to achieve this operatically simple process is the use of Pd catalysis, which could tolerate the solvent and acidic conditions used in the thianthrenation step. This protocol features mild conditions, broad functional group tolerance, and simple manipulations, and is suitable for late-stage functionalization of a wide range of pharmaceuticals and complex bioactive molecules.

METHOD FOR THE PRODUCTION OF LOSARTAN

-

Page/Page column 20; 32, (2008/06/13)

The invention relates to a novel method for the production of losartan, an imidazol derivative with the chemical name 2-n-butyl-4-chloro-5-hydroxymethyl-1-{[2'-(1H-tetrazol-5-yl)biphenyl-4-]methyl}imidazol and the pharmacologically active salts thereof. The invention also relates to novel intermediate products which are suitable for the production of losartan, and to novel methods for the production of intermediate compounds which are suitable for the production of losartan. One aspect of the invention is a method for the production of a compound of general formula (I), which can arise as an intermediate step in the inventive representation of losartan.
