Check Digit Verification of cas no

The CAS Registry Mumber 2851-82-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,5 and 1 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 2851-82:
(6*2)+(5*8)+(4*5)+(3*1)+(2*8)+(1*2)=93
93 % 10 = 3
So 2851-82-3 is a valid CAS Registry Number.

Aqueous Synthesis of 14-15-Membered Crown Ethers with Mixed O, N and S Heteroatoms: Experimental and Theoretical Binding Studies with Platinum-Group Metals

Torrejos, Rey Eliseo C.,Nisola, Grace M.,Min, Sang Hoon,Han, Jeong Woo,Koo, Sangho,Parohinog, Khino J.,Lee, Seongpoong,Kim, Hern,Chung, Wook-Jin

, p. 210 - 221 (2019)

A series of 14-15-membered O, N, and S-containing crown ethers (CEs) was synthesized by cyclization of bis-epoxides with aryl-N or S dinucleophiles using triethylamine as a catalyst and LiCl as a metal template in water. The catalyst dosage, and metal template type and dosage were critical in achieving yields of 56–93 %. Liquid-liquid extraction (LLE) was performed to evaluate the CE complexation with Pd2+ and Pt2+. Among the CEs, a dioxa-dithia dibenzo CE exhibited the highest Pd2+ selectivity even in the presence of other platinum-group metals (PGMs). Complementary DFT studies reveal that this CE has the most compatible cavity dimension (?CE=1.58 ?) with Pd2+ (?Pd2+=1.56 ?) forming a square-planar S4 geometry. Binding-energy calculations showed the Pd2+ complex has the least energy requirement for structural reorientation during complexation. Overall results highlight the importance of CE cavity dimension and presence of S heteroatoms for the structural design of CEs selective towards PGMs such as Pd2+.

Macroheterocycles. Part 42. A Facile Synthesis of Dihydroxy Cryptands and their Dehydroxylation

Lukyanenko, Nikolay G.,Reder, Anatoly S.

, p. 2533 - 2536 (1988)

A facile synthesis of hydroxy cryptands by the reaction of diglycidyl ethers with a diazacrown ether is reported.The reaction results in a mixture of bi- and tri-cyclic cryptands which can be separated by chromatography.The yield of bicyclic cryptands is lowered with a decrease in the diazacrown ether cycle size and an increase in the number of oxyethylene moieties between the epoxy groups in the diglycidyl ether.The results are interpreted in terms of the intramolecular hydrogen bonding of epoxy groups promoting the steric fixation of the reaction centres.Dehydroxylation of the bicyclic dihydroxy cryptands has been performed by means of chlorination followed by reduction.
