381665-52-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 381665-52-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,8,1,6,6 and 5 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 381665-52:
(8*3)+(7*8)+(6*1)+(5*6)+(4*6)+(3*5)+(2*5)+(1*2)=167
167 % 10 = 7
So 381665-52-7 is a valid CAS Registry Number.

Total synthesis of fostriecin (CI-920)
Chavez, David E.,Jacobsen, Eric N.
, p. 3667 - 3670 (2007/10/03)
The most selective protein phosphatase inhibitor identified to date, fostriecin was synthesized in a highly convergent manner by a chiral building block approach (see picture). Three of the four stereocenters were introduced by using catalytic methods, in
