Check Digit Verification of cas no

The CAS Registry Mumber 163974-99-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,3,9,7 and 4 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 163974-99:
(8*1)+(7*6)+(6*3)+(5*9)+(4*7)+(3*4)+(2*9)+(1*9)=180
180 % 10 = 0
So 163974-99-0 is a valid CAS Registry Number.

Beitraege zur Chemie des bors, 226: Funktionalisierung von Alkinylboranen-Umsetzung mit Nucleophilen

Feulner, Herta,Metzler, Nils,Noeth, Heinrich

, p. 51 - 62 (1995)

The synthesis of alkynylboranes RR'B-CC-R" 1-3 and their reactions with various nucleophiles are described (R, R' = Me2N, Cl, alkyl; R" = Me, Ph).Although these compounds can be looked upon as inorganic Michael systems, nucleophiles such as alcohols, amines, amides and various carbon nucleophiles attack exclusively at the boron atom (analogous to a 1,2- attack).Thus, a nonvenient means of functionalization of alkynylboranes at the boron atom with preservation of the B-CC moiety is described, and alkynylboranes with R,R' = Me2N, N(H)iPr, pyr, OiPr, Me, Mes, CC-SiMe3 were obtained in good yield and characterized by spectroscopic methods.The pathway for the reaction of (Me2N)2B-CC-Ph with carbon nucleophiles to tris(alkyl)boranes has been elucidated.The implications both for the electronic properties and the chemical reactivity of alkynylboranes are discussed.Keywords: Alkynylboranes, Nucleophilic attack, Organoboron compounds, Inorganic Michael systems; Boron; Alkyne
