Calculate Digit Verification of CAS Registry Number 1609200-16:
(9*1)+(8*6)+(7*0)+(6*9)+(5*2)+(4*0)+(3*0)+(2*1)+(1*6)=129
129 % 10 = 9
So 1609200-16-9 is a valid CAS Registry Number.

supporting information, p. 5782 - 5785 (2014/05/20)

Total synthesis of (+)-kopsihainanine A was accomplished on the basis of (i) Stoltz's enantioselective decarboxylative asymmetric allylation and (ii) the proposed biogenetic pathway from the related alkaloid, kopsihainanine B. In addition, HPLC analysis of the synthetic (+)-kopsihainanine A confirmed its ee to be 99% with [α]30D = 25.35. the Partner Organisations 2014.
