173425-83-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 173425-83-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,3,4,2 and 5 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 173425-83:
(8*1)+(7*7)+(6*3)+(5*4)+(4*2)+(3*5)+(2*8)+(1*3)=137
137 % 10 = 7
So 173425-83-7 is a valid CAS Registry Number.

An approach to pancratistatin from myo-inositol
Gauthier Jr., Donald R.,Bender, Steven L.
, p. 13 - 16 (2007/10/02)
A highly advanced intermediate (15) for the synthesis of 7-deoxypancratistatin was prepared in 11 steps from myo-inositol. Introduction of the C(10b)-Ar bond through an intramolecular epoxide opening with an aryl anion is the key step in this approach.
