Check Digit Verification of cas no

The CAS Registry Mumber 649571-82-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,9,5,7 and 1 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 649571-82:
(8*6)+(7*4)+(6*9)+(5*5)+(4*7)+(3*1)+(2*8)+(1*2)=204
204 % 10 = 4
So 649571-82-4 is a valid CAS Registry Number.
