891491-89-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 891491-89-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,1,4,9 and 1 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 891491-89:
(8*8)+(7*9)+(6*1)+(5*4)+(4*9)+(3*1)+(2*8)+(1*9)=217
217 % 10 = 7
So 891491-89-7 is a valid CAS Registry Number.

A highly enantioselective total synthesis of (+)-goniodiol
Tate, Edward W.,Dixon, Darren J.,Ley, Steven V.
, p. 1698 - 1706 (2008/02/11)
A high-yielding enantioselective total synthesis of the bioactive styryllactone (+)-goniodiol has been realised, starting from readily available (S)-glycidol. A key step is an oxygen-to-carbon rearrangement of a silyl enol ether linked via an anomeric cen
