216769-50-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 216769-50-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,6,7,6 and 9 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 216769-50:
(8*2)+(7*1)+(6*6)+(5*7)+(4*6)+(3*9)+(2*5)+(1*0)=155
155 % 10 = 5
So 216769-50-5 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
