Check Digit Verification of cas no

The CAS Registry Mumber 648407-89-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,8,4,0 and 7 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 648407-89:
(8*6)+(7*4)+(6*8)+(5*4)+(4*0)+(3*7)+(2*8)+(1*9)=190
190 % 10 = 0
So 648407-89-0 is a valid CAS Registry Number.
