23434-97-1 Usage
Description
The aerial portions of Thalictrum minus yield this alkaloid which has been
shown to possess the structure of 1: 2-dihydro-5: 6: 7-trimethoxy-2-methyl-loxoisoquinoline. It gives an ultraviolet spectrum in EtOH with absorption
maxima at 247, 270, 281, 293 and 332 nm. The base is stable to both acid
and alkaline hydrolysis and hydrogenation with LiAlH4,NaBH4 or PtO2 up
to 100°C but catalytic hydrogenation at 80°C and 80 atmospheres furnishes
the dihydro derivative, m.p. 104-6°C.

Check Digit Verification of cas no
The CAS Registry Mumber 23434-97-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,4,3 and 4 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 23434-97:
(7*2)+(6*3)+(5*4)+(4*3)+(3*4)+(2*9)+(1*7)=101
101 % 10 = 1
So 23434-97-1 is a valid CAS Registry Number.

We have worked out a very short approach to 1-oxoisoquinoline alkaloids starting from readily available 2-bromobenzamides utilizing a 2-ethoxyvinylboronate as a C2 building block for introduction of the C-3,C-4 unit of the isoquinoline core. TF
