131407-11-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131407-11-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,4,0 and 7 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 131407-11:
(8*1)+(7*3)+(6*1)+(5*4)+(4*0)+(3*7)+(2*1)+(1*1)=79
79 % 10 = 9
So 131407-11-9 is a valid CAS Registry Number.

Enantiopure Didemnenones via Kinetic Resolution
Goeres, Markus,Winterfeldt, Ekkehard
, p. 3525 - 3532 (2007/10/02)
Kinetic resolution in an enantioselective Diels-Alder process provided the starting material for an imporved and simplified approach to all the didemnenones via the lactone 16.
