900807-30-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 900807-30-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,0,8,0 and 7 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 900807-30:
(8*9)+(7*0)+(6*0)+(5*8)+(4*0)+(3*7)+(2*3)+(1*0)=139
139 % 10 = 9
So 900807-30-9 is a valid CAS Registry Number.

Synthesis of nonactin and the proposed structure of trilactone
Wu, Yikang,Sun, Ya-Ping
, p. 2831 - 2834 (2007/10/03)
An efficient enantioselective route to nonactin using a novel β-inversion of an Evans syn aldol to construct the THF ring is presented. Through total synthesis, the structure for trilactone proposed in the literature is shown likely to be incorrect.
