Check Digit Verification of cas no

The CAS Registry Mumber 189999-72-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,9,9 and 9 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 189999-72:
(8*1)+(7*8)+(6*9)+(5*9)+(4*9)+(3*9)+(2*7)+(1*2)=242
242 % 10 = 2
So 189999-72-2 is a valid CAS Registry Number.

Copper(I) iodide-catalyzed regioselective allylation of α-(2-pyridylthio)allylstannanes. A new route to δ,ε-unsaturated ketones

Takeda, Takeshi,Matsunaga, Ko-Ichi,Uruga, Tetsuya,Takakura, Michiyo,Fujiwara, Tooru

, p. 2879 - 2882 (1997)

The reaction of α-(2-pyridylthio)allylstannanes with allylic halides in the presence of a catalytic amount of copper(I) iodide in DMSO-THF produced the 1,5-dienes 3 in good yields. The γ-selective allylation using allyl chloride followed hy the alkylation and hydrolysis of resulting vinyl sulfides gave δ,ε-unsaturated ketones.
