53137-51-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 53137-51-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,1,3 and 7 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 53137-51:
(7*5)+(6*3)+(5*1)+(4*3)+(3*7)+(2*5)+(1*1)=102
102 % 10 = 2
So 53137-51-2 is a valid CAS Registry Number.

Application of aryl siloxane cross-coupling to the synthesis of allocolchicinoids
Seganish, W. Michael,DeShong, Philip
, p. 3951 - 3954 (2007/10/03)
In this communication, we report a new approach to the allocolchicine carbocyclic skeleton based upon an aryl siloxane coupling reaction and a phenanthrol ring expansion. These key steps allow for the selective functionalization of every carbon within the
