Check Digit Verification of cas no

The CAS Registry Mumber 13730-34-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,7,3 and 0 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 13730-34:
(7*1)+(6*3)+(5*7)+(4*3)+(3*0)+(2*3)+(1*4)=82
82 % 10 = 2
So 13730-34-2 is a valid CAS Registry Number.

Thermochemistry of Perthiyl Radicals

Hawari, J. A.,Griller, D.,Lossing, F. P.

, p. 3273 - 3275 (1986)

Mass spectrometry was used to measure appearance energies for the reaction RSS-t-Bu -> RSS. + t-Bu+ for R = Me, Et, i-Pr, and t-Bu.The data lead to the heats of formation of perthiyl radicals, RSS., and hence to S-C bond dissociation energies in disulfides (ca. 54 kcal mol-1) and to S-S bond dissociation energies for the central bonds of tetrasulfides (32.3 +/- 1.0 kcal mol-1).The appearance energy method was also used to measure the ionization energy of t-BuSS. (8.25 +/- 0.08 eV) and the heat of formation of the ion t-BuSS+ (195 +/- 2 kcal mol-1).

From symmetrical tetrasulfides to trisulfide dioxides: Via photocatalysis

Gong, Kai,Jiang, Xuefeng,Zhou, Yilin

supporting information, p. 9865 - 9869 (2021/12/24)

A straightforward strategy involving photocatalysis has been established for accessing trisulfide dioxides from readily achieved symmetrical tetrasulfides. Stern-Volmer analysis and radical quenching experiments demonstrated the occurrence of a single electron transfer between the photocatalyst and sulfinic acid. Bioactive molecules such as the antihypertensive drug captopril, allicin derivatives, amino acids and terpenes were efficiently and reversibly linked through sulfur-sulfur covalent bonds. Furthermore, flow-setup syntheses of trisulfide dioxides were successfully achieved on the gram scale, indicating the great potential of the developed protocol for practical industrial applications.

Insertion of a two sulfur unit into the S-S bond - Tailor-made polysulfides

Rys,Harpp

, p. 7169 - 7172 (2007/10/03)

Triphenylthiosulfenyl chloride (1) reacts with disulfides RSSR, yielding tetrasulfides as the main products. The results of the insertion for different R groups are reported. A two-step mechanism involving the formation of unsymmetrical trisulfide intermediates containing the trityl group is proposed. (C) 2000 Elsevier Science Ltd.

Formation of dialkyl polysulfides from vinyl ethers in the system H2S-DMSO-MOH

Musorin,Sedunova,Trofimov

, p. 794 - 797 (2007/10/03)

The reaction of vinyl ethers with the system H2S-DMSO-MOH (30°C, 5 h) gives dialkyl polysulfides with a total yield of up to 65% instead of expected oxygen-containing thiols and sulfides. The ratio between dialkyl di-, tri-, and tetrasulfides depends on the nature of the vinyl ether and on the amount of alkali metal hydroxide in the reaction mixture. With di(propen-1-yl) ether, 4-methyl-2-ethyl-1,3-oxathiolane was also found as a by-product.
