Check Digit Verification of cas no

The CAS Registry Mumber 1417202-95-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,7,2,0 and 2 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1417202-95:
(9*1)+(8*4)+(7*1)+(6*7)+(5*2)+(4*0)+(3*2)+(2*9)+(1*5)=129
129 % 10 = 9
So 1417202-95-9 is a valid CAS Registry Number.

Synthesis, characterization, and oxidation electrochemistry of some novel 1,2-dithiol-3-ones and 1,2-dithiol-3-thiones containing aryl and metallocenyl fragments

Sánchez García, Jessica J.,Joo-Cisneros, Rene S.,García-Bassoco, David,Flores-Alamo, Marcos,Stivalet, José M. Méndez,García-Valdés, Jesús,Klimova, Elena I.

, (2021)

A new synthesis method was established for 1,2-dithiol-3-ones and 1,2-dithiol-3-thiones, from different cyclopropenones: diphenyl (a), bis-(4-methoxyphenyl (b), diferrocenyl (c) and diruthenocenyl (d), in the presence of elemental sulfur with yields of the 5a-d (35–57%), or in the presence of the additive NaHS, with yields of the 5a-d (45–72%) and 6a-d (10–18%). The characterization of the new compounds was conducted by IR, 1H and 13C NMR spectroscopy, elemental analysis, mass-spectrometry. In addition, X-ray crystallographic analysis of the compounds 5a,b,d was conducted. The redox properties of the heterocyclic compounds were investigated using cyclic (CV), differential pulse (DPV) and square wave (SWV) voltammetries.
