225642-64-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 225642-64-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,5,6,4 and 2 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 225642-64:
(8*2)+(7*2)+(6*5)+(5*6)+(4*4)+(3*2)+(2*6)+(1*4)=128
128 % 10 = 8
So 225642-64-8 is a valid CAS Registry Number.

Enantioselective total synthesis of (+)-obtusenyne
Crimmins, Michael T.,Powell, Mark T.
, p. 7592 - 7595 (2007/10/03)
A total synthesis of the laurencia metabolite (+)-obtusenyne has been completed. The key steps include a Sharpless kinetic resolution and an asymmetric glycolate alkylation to establish the stereogenic centers adjacent to the ether linkage and a ring-clos
