1244032-46-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1244032-46-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,4,0,3 and 2 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1244032-46:
(9*1)+(8*2)+(7*4)+(6*4)+(5*0)+(4*3)+(3*2)+(2*4)+(1*6)=109
109 % 10 = 9
So 1244032-46-9 is a valid CAS Registry Number.

A concise asymmetric synthesis of (-)-hongconin and (-)-1-epi-hongconin
Fernandes, Rodney A.,Chavan, Vijay P.
experimental part, p. 4306 - 4311 (2010/10/19)
A concise asymmetric synthesis of (-)-hongconin and (-)-1epi-hongconin is described. The synthesis features an efficient combination of Doetz benzannulation or lactaldehyde arylation and the oxa-Pictet-Spengler reaction as the key steps. The synthesis is
