Check Digit Verification of cas no
The CAS Registry Mumber 143121-46-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,1,2 and 1 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 143121-46:
(8*1)+(7*4)+(6*3)+(5*1)+(4*2)+(3*1)+(2*4)+(1*6)=84
84 % 10 = 4
So 143121-46-4 is a valid CAS Registry Number.

Broka, Chris A.,Ruhland, Beatrice
, p. 4888 - 4894 (2007/10/02)
This report describes the first synthesis of the highly reactive furanocyclohexadienone lactone subunit of the natural products wortmannin (1) and 11-desacetoxywortmannin (2).The simplified wortmannin analogue 6 was prepared by acid treatment of aminometh
