The CAS Registry Mumber 163189-52-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,3,1,8 and 9 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 163189-52:
(8*1)+(7*6)+(6*3)+(5*1)+(4*8)+(3*9)+(2*5)+(1*2)=144
144 % 10 = 4
So 163189-52-4 is a valid CAS Registry Number.

A Reaction of γ-Chalcogen-substituted Prop-2-ynyl Cations with Mild Nucleophiles

Yoshimatsu, Mitsuhiro,Shimizu, Hiroshi,Kataoka, Tadashi

, p. 149 - 150 (1995)

γ-Chalcogen-substituted prop-2-ynyl cations are generated by the reactions of diethyl acetals 1 and 2 with BF3-Et2O and react with various mild nucleophiles without isomerisation to allenyl cations to afford the prop-2-ynylated products 3a-e and 5a-c in good yields.
