Check Digit Verification of cas no

The CAS Registry Mumber 884318-78-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,4,3,1 and 8 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 884318-78:
(8*8)+(7*8)+(6*4)+(5*3)+(4*1)+(3*8)+(2*7)+(1*8)=209
209 % 10 = 9
So 884318-78-9 is a valid CAS Registry Number.

supporting information, p. 4213 - 4216 (2016/08/25)

Urumamide, a novel cyclic depsipeptide that contains a β-amino acid, was isolated from a marine cyanobacterium Okeania sp. Its gross structure was determined by spectroscopic analyses, and the absolute configuration was established based on Marfey's analyses and chiral HPLC analyses of hydrolysis products. Biologically, urumamide inhibited the growth of human cancer cells. In addition, urumamide inhibited chymotrypsin.
