Check Digit Verification of cas no

The CAS Registry Mumber 439292-93-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,9,2,9 and 2 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 439292-93:
(8*4)+(7*3)+(6*9)+(5*2)+(4*9)+(3*2)+(2*9)+(1*3)=180
180 % 10 = 0
So 439292-93-0 is a valid CAS Registry Number.

supporting information; experimental part, p. 733 - 736 (2009/09/30)

(Chemical Equation Presented) Asymmetric total syntheses of (+)-azinothricin and (+)-kettapeptin have been completed through a common new pathway that exploits a highly chemoselective coupling reaction between the fully elaborated cyclodepsipeptide 5 and the glycal activated esters 3 and 4 at the final stages of both respective syntheses.
