691905-80-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 691905-80-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,9,1,9,0 and 5 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 691905-80:
(8*6)+(7*9)+(6*1)+(5*9)+(4*0)+(3*5)+(2*8)+(1*0)=193
193 % 10 = 3
So 691905-80-3 is a valid CAS Registry Number.

Synthesis of Putative Uniflorine A
Davis, Andrew S.,Pyne, Stephen G.,Skelton, Brian W.,White, Allan H.
, p. 3139 - 3143 (2007/10/03)
A diastereoselective synthesis of the putative structure of the natural product uniflorine A has been achieved by using the Petasis borono-Mannich reaction and ring-closing metathesis as key steps. The NMR data of the synthetic material did not match that
