557077-72-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 557077-72-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,5,7,0,7 and 7 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 557077-72:
(8*5)+(7*5)+(6*7)+(5*0)+(4*7)+(3*7)+(2*7)+(1*2)=182
182 % 10 = 2
So 557077-72-2 is a valid CAS Registry Number.

Total synthesis of the spermidine alkaloid 13-hydroxyisocyclocelabenzine
Li, Yi,Linden, Anthony,Hesse, Manfred
, p. 579 - 591 (2007/10/03)
A convergent total synthesis of 13-hydroxyisocyclocelabenzine was developed. (3S)-Methyl 3-amino-3-phenylpropanoate (4) was used as the chiral building block. The 3,4-dihydro-4-hydroxyisoquinolin-1(2H)-one derivative (5), the key fragment for the total sy
