199525-13-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 199525-13-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,9,5,2 and 5 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 199525-13:
(8*1)+(7*9)+(6*9)+(5*5)+(4*2)+(3*5)+(2*1)+(1*3)=178
178 % 10 = 8
So 199525-13-8 is a valid CAS Registry Number.

Total synthesis of dysidiolide
Corey,Roberts, Bryan E.
, p. 12425 - 12431 (2007/10/03)
The cdc25A protein phosphatase inhibitor dysidiolide (1) has been synthesized enantioselectively, starting from the enantiomerically pure ketal enone 2 and using a cationic rearrangement as the key step to produce the fully substituted bicyclic core of th
