309714-48-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 309714-48-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,9,7,1 and 4 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 309714-48:
(8*3)+(7*0)+(6*9)+(5*7)+(4*1)+(3*4)+(2*4)+(1*8)=145
145 % 10 = 5
So 309714-48-5 is a valid CAS Registry Number.

Synthesis of model of phomopsin-ustiloxin-type antimitotic agents
Laib,Zhu
, p. 1363 - 1365 (2007/10/03)
An intramolecular S(N)Ar reaction was applied to the synthesis of a 13-membered meta-cyclophane that is the structural core of phomopsin and ustiloxin-type antimitotics. Two types of facile β-elimination processes are also documented.
