Check Digit Verification of cas no

The CAS Registry Mumber 304874-60-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,4,8,7 and 4 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 304874-60:
(8*3)+(7*0)+(6*4)+(5*8)+(4*7)+(3*4)+(2*6)+(1*0)=140
140 % 10 = 0
So 304874-60-0 is a valid CAS Registry Number.
