Check Digit Verification of cas no

The CAS Registry Mumber 486449-97-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,8,6,4,4 and 9 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 486449-97:
(8*4)+(7*8)+(6*6)+(5*4)+(4*4)+(3*9)+(2*9)+(1*7)=212
212 % 10 = 2
So 486449-97-2 is a valid CAS Registry Number.

Ulongapeptin, a cytotoxic cyclic depsipeptide from a Palauan marine cyanobacterium Lyngbya sp.

Williams, Philip G.,Yoshida, Wesley Y.,Quon, Michael K.,Moore, Richard E.,Paul, Valerie J.

, p. 651 - 654 (2003)

Ulongapeptin (1), a cyclic depsipeptide, was isolated from a Palauan marine cyanobacterium Lyngbya sp. The gross structure was elucidated through one-dimensional TOCSY experiments and other spectroscopic techniques. The absolute and relative stereochemistry of the β-amino acid, 3-amino-2-methyl-7-octynoic acid (AMO), in 1 was determined by synthesis of the saturated α-alkyl-β-amino acid and Marfey's analysis of the acid hydrolysate of tetrahydro-1. Ulongapeptin (1) was cytotoxic against KB cells at an IC50 value of 0.63 μM.
