Check Digit Verification of cas no

The CAS Registry Mumber 18729-57-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,7,2 and 9 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 18729-57:
(7*1)+(6*8)+(5*7)+(4*2)+(3*9)+(2*5)+(1*7)=142
142 % 10 = 2
So 18729-57-2 is a valid CAS Registry Number.

Oxidative coupling of dichalcogenides with sodium sulfinates via copper-catalyzed cleavage of s-s and se-se bonds

Taniguchi, Nobukazu

, p. 1764 - 1770 (2015)

A copper-catalyzed sulfonylation of disulfides was achieved using sodium sulfinates in air. The reaction formed various sulfur-sulfone bonds efficiently and afforded thiosulfonates in good yields. Selenosulfonates could also be prepared with this procedure. Furthermore, both chalcogenide groups on the dichalcogenides were available in these reactions.

Copper-catalyzed synthesis of thiosulfonates by oxidative coupling of thiols with sodium sulfinates

Taniguchi, Nobukazu

supporting information, p. 5691 - 5694 (2014/11/07)

The copper-catalyzed sulfonylation of thiols was performed by using sodium sulfinates under an oxygen atmosphere. The procedure afforded thiosulfonates in good yields by using a CuI-Phen?H2O (Phen = 1,10-phenanthroline) catalyst and tolerated numerous combinations of arene- and alkanethiols with sodium sulfinates. Furthermore, it was found that the coupling of diaryl disulfides with sodium arylsulfinates proceeded in air and both sulfide groups on the disulfide were available.
