1254252-87-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1254252-87-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,4,2,5 and 2 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1254252-87:
(9*1)+(8*2)+(7*5)+(6*4)+(5*2)+(4*5)+(3*2)+(2*8)+(1*7)=143
143 % 10 = 3
So 1254252-87-3 is a valid CAS Registry Number.

Total synthesis of clathculins A and B
Hoye, Rebecca C.,Anderson, Gretchen L.,Brown, Susan G.,Schultz, Erica E.
experimental part, p. 7400 - 7403 (2011/02/22)
Clathculins A and B represent a new class of vic-diamine alkaloids containing a PA2 unit as the basic structure. We report the first total syntheses of 1 and 2, which confirm the assigned structure of each. Dependence of their NMR spectroscopic behavior a
