Check Digit Verification of cas no

The CAS Registry Mumber 586976-83-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,8,6,9,7 and 6 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 586976-83:
(8*5)+(7*8)+(6*6)+(5*9)+(4*7)+(3*6)+(2*8)+(1*3)=242
242 % 10 = 2
So 586976-83-2 is a valid CAS Registry Number.

Total synthesis and assignment of the double-bond position and absolute configuration of (-)-pyrinodemin A

Morimoto, Yoshiki,Kitao, Satoru,Okita, Tatsuya,Shoji, Takamasa

, p. 2611 - 2614 (2007/10/03)

(Matrix presented) The first asymmetric total synthesis of a structurally novel cis-cyclopent[c]isoxazolidine alkaloid, (-)-pyrinodemin A (3), which exhibits potent cytotoxicity, has been accomplished through a highly diastereoselective intramolecular nitrone - olefin cycloaddition reaction as the key step. Thus, it has been found that the hitherto unknown absolute configuration of pyrinodemin A is as indicated in the structural formula 3.
