90330-67-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 90330-67-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,3,3 and 0 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 90330-67:
(7*9)+(6*0)+(5*3)+(4*3)+(3*0)+(2*6)+(1*7)=109
109 % 10 = 9
So 90330-67-9 is a valid CAS Registry Number.

CROSS DIENE-TRANSMISSIVE DIELS-ALDER CYCLOADDITION REACTION OF BIS(SILYLOXY) CROSS-CONJUGATED TRIENES.

Tsuge,Kanemasa,Sakoh,Wada

, p. 3234 - 3241 (2007/10/02)

Cross type of diene-transmissive Diels-Alder cycloaddition has been demonstrated by using two bis-silyloxy cross-conjugated trienes. The first cycloaddition stage of cross reaction, which has to be highly selective in the formation of mono-cycloadducts, h

CROSS TYPE OF DIENE-TRANSMISSIVE DIELS-ALDER REACTION

Tsuge, Otohiko,Kanemasa, Shuji,Sakoh, Hirohiko,Wada, Eiji

, p. 277 - 278 (2007/10/02)

The first example of cross type of diene-transmissive Diels-Alder reaction is presented by the reactions of an activated cross-conjugated triene, 3-(methoxymethylene)-2,4-bis(trimethylsilyloxy)-1,4-pentadiene, with cyclic olefins as the first dienophiles and then with acetylenes as the second.
