Check Digit Verification of cas no

The CAS Registry Mumber 1035457-84-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,3,5,4,5 and 7 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1035457-84:
(9*1)+(8*0)+(7*3)+(6*5)+(5*4)+(4*5)+(3*7)+(2*8)+(1*4)=141
141 % 10 = 1
So 1035457-84-1 is a valid CAS Registry Number.

The case for the intermediacy of monomeric metaphosphate analogues during oxidation of H-phosphonothioate, H-phosphonodithioate, and H-phosphonoselenoate monoesters: Mechanistic and synthetic studies

Bartoszewicz, Agnieszka,Kalek, Marcin,Stawinski, Jacek

, p. 5029 - 5038 (2008/12/20)

(Chemical Equation Presented) Studies on the reaction of H-phosphonothioate, H-phosphonodithioate, and H-phosphonoselenoate monoesters with iodine in the presence of a base led to identification of a unique oxidation pathway, which consists of the initial oxidation of the sulfur or selenium atom in these compounds, followed by oxidative elimination of hydrogen iodide to generate the corresponding metaphosphate analogues. The intermediacy of the latter species during oxidation of the investigated H-phosphonate monoester derivatives with iodine was supported by various diagnostic experiments. The scope and limitation of these oxidative transformations for the purpose of the synthesis of nucleoside phosphorothioate, nucleoside phosphorodithioate, and nucleoside phosphoroselenoate diesters was also investigated.
