Check Digit Verification of cas no

The CAS Registry Mumber 639857-68-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,9,8,5 and 7 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 639857-68:
(8*6)+(7*3)+(6*9)+(5*8)+(4*5)+(3*7)+(2*6)+(1*8)=224
224 % 10 = 4
So 639857-68-4 is a valid CAS Registry Number.
