53905-56-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 53905-56-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,9,0 and 5 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 53905-56:
(7*5)+(6*3)+(5*9)+(4*0)+(3*5)+(2*5)+(1*6)=129
129 % 10 = 9
So 53905-56-9 is a valid CAS Registry Number.

One-pot triangular chemoenzymatic cascades for the syntheses of chiral alkaloids from dopamine
Lichman,Lamming,Pesnot,Smith,Hailes,Ward
, p. 852 - 855 (2015/03/04)
We describe novel chemoenzymatic routes to (S)-benzylisoquinoline and (S)-tetrahydroprotoberberine alkaloids using the enzymes transaminase (TAm) and norcoclaurine synthase (NCS) in a one-pot, one-substrate 'triangular' cascade. Employment of up to two C-
