Check Digit Verification of cas no

The CAS Registry Mumber 81206-75-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,2,0 and 6 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 81206-75:
(7*8)+(6*1)+(5*2)+(4*0)+(3*6)+(2*7)+(1*5)=109
109 % 10 = 9
So 81206-75-9 is a valid CAS Registry Number.

Diels-Alder Reactions of (Trifluoromethyl)ethene and (Trifluoromethyl)styrenes with Functionalized Butadiens

Ojima, Iwao,Yatabe, Momoko,Fuchikami, Takamasa

, p. 2051 - 2055 (2007/10/02)

The-Alder reactions of (trifluoromethyl)ethene (1) with 2-(trimethylsiloxy)buta-1,3-diene (2), 2--1,3-butadiene (4), and 1-methoxy-3-(trimethylsiloxy)buta-1,3-diene (6) were carried out to give the corresponding cycloadducts in 17-38percent yields.It was found that the former two cycloadducts were a mixture of para (major) and meta (minor) isomers, while the latter was the para isomer exlusively.Similary, β-(trifluoromethyl)-4-(methoxycarbonyl)styrene (9) and β-(trifluoromethyl)-4-nitrostyrene (10) were allowed to react with 4 and 6, giving the corresponding cycloadducts in 56-90percent yields.The regioselectivity of the reaction on using 6 as the diene turned out to be extremely high, leading to the formation of only one regioisomer.The substituent effect of the trifluoromethyl group in the Diels-Alder reaction in terms of regioselectivity is discussed.
