56570-46-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 56570-46-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,5,7 and 0 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 56570-46:
(7*5)+(6*6)+(5*5)+(4*7)+(3*0)+(2*4)+(1*6)=138
138 % 10 = 8
So 56570-46-8 is a valid CAS Registry Number.

In contrast with their oxo-analogues, thioenamides undergo photochemical cyclization to yield isoquinolinethione derivatives which are easily converted into isoquinolones and tetrahydroisoquinolines by treatment with benzeneseleninic anhydride and EtO3BF4
