729572-41-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 729572-41-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,2,9,5,7 and 2 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 729572-41:
(8*7)+(7*2)+(6*9)+(5*5)+(4*7)+(3*2)+(2*4)+(1*1)=192
192 % 10 = 2
So 729572-41-2 is a valid CAS Registry Number.

Synthesis of (±)-aporphine utilizing Pictet-Spengler and intramolecular phenol ortho-arylation reactions
Cuny, Gregory D.
, p. 5167 - 5170 (2004)
A synthesis of the alkaloid (±)-aporphine is reported. The initial key step of the synthesis involves a Pictet-Spengler cyclization of N-tosyl tyramine with 2-bromophenylacetaldehyde in trifluoroacetic acid. This step was followed by the second strategic
