Check Digit Verification of cas no

The CAS Registry Mumber 50337-59-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,3,3 and 7 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 50337-59:
(7*5)+(6*0)+(5*3)+(4*3)+(3*7)+(2*5)+(1*9)=102
102 % 10 = 2
So 50337-59-2 is a valid CAS Registry Number.

Catalyst-free visible light-mediated selective oxidation of sulfides into sulfoxides under clean conditions

Fan, Qiangwen,Zhu, Longwei,Li, Xuhuai,Ren, Huijun,Wu, Guorong,Zhu, Haibo,Sun, Wuji

supporting information, p. 7945 - 7949 (2021/11/01)

A facile and efficient visible-light-mediated method for directly converting sulfides into sulfoxides under clean conditions without using any photocatalysts is reported. This method exhibited favourable compatibility with functional groups and afforded a series of sulfoxides with high selectivity and yields. Moreover, in order to shed more light on such a transformation, detailed mechanism studies were carried out both experimentally and theoretically. The readily accessible, low-cost and eco-friendly nature of the developed method will endow it with attractive applications in chemical synthesis.

Synergistic cooperative effect of CF3SO2Na and bis(2-butoxyethyl)ether towards selective oxygenation of sulfides with molecular oxygen under visible-light irradiation

Liu, Kai-Jian,Wang, Zheng,Lu, Ling-Hui,Chen, Jin-Yang,Zeng, Fei,Lin, Ying-Wu,Cao, Zhong,Yu, Xianyong,He, Wei-Min

supporting information, p. 496 - 500 (2021/01/28)

A safe, practical and eco-friendly method for the switchable synthesis of sulfoxides and sulfones through visible-light-initiated oxygenation of sulfides at ambient temperature under transition-metal-, additives-free and minimal solvent conditions. The synergistic catalytic efforts between CF3SO2Na and 2-butoxyethyl ether represents the key promoting factor for the reaction. This journal is

Flow Electrosynthesis of Sulfoxides, Sulfones, and Sulfoximines without Supporting Electrolytes

Amri, Nasser,Wirth, Thomas

, p. 15961 - 15972 (2021/07/20)

An efficient electrochemical flow process for the selective oxidation of sulfides to sulfoxides and sulfones and of sulfoxides toN-cyanosulfoximines has been developed. In total, 69 examples of sulfoxides, sulfones, andN-cyanosulfoximines have been synthesized in good to excellent yields and with high current efficiencies. The synthesis was assisted and facilitated through a supporting electrolyte-free, fully automated electrochemical protocol that highlights the advantages of flow electrolysis.
