121731-72-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 121731-72-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,7,3 and 1 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 121731-72:
(8*1)+(7*2)+(6*1)+(5*7)+(4*3)+(3*1)+(2*7)+(1*2)=94
94 % 10 = 4
So 121731-72-4 is a valid CAS Registry Number.

Synthesis of the Chiral (8S)-7-Aza-1,3(E),9-decatriene System from Natural α-Amino Acids and Its Intramolecular Diels-Alder Reaction Directed toward Chiral trans-Hydroisoquinolones

Moriwake, Toshio,Hamano, Shin-ich,Saito, Seiki,Torii, Shigeru,Kashino, Setsuo

, p. 4114 - 4120 (2007/10/02)

L-Alanine and L-valine were converted into optically active 7-aza-1,3(E),9-decatrienes containing a (tert-butyldimethylsilyl)oxy group at C(2) and a methyl or isopropyl group at C(8).Intramolecular thermal cycloaddition reactions of these trienes gave optically active trans-nonahydro-6(2H)-isoquinolones.The relatively bulky isopropyl group at C(8) increased the trans selectivity in the ring closure.These results are in contrast with literature reports on ring closure of analogous aza trienes that lack the (tert-butyldimethylsilyl)oxy group at C(2), whichgive predominantly cis-fused rings.
