228396-12-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 228396-12-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,8,3,9 and 6 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 228396-12:
(8*2)+(7*2)+(6*8)+(5*3)+(4*9)+(3*6)+(2*1)+(1*2)=151
151 % 10 = 1
So 228396-12-1 is a valid CAS Registry Number.

Asymmetric routes to the trisporic acids via chiral bicyclic lactams
Reeder, Michael R.,Meyers
, p. 3115 - 3118 (2007/10/03)
Two synthetic approaches to the title compounds using the chiral non- racemic lactam 3 via additions to the lactam carbonyl lead to the requisite chiral cyclohexen-2-ones.
