Check Digit Verification of cas no

The CAS Registry Mumber 639852-53-2 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 2 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 639852-53:
(8*6)+(7*3)+(6*9)+(5*8)+(4*5)+(3*2)+(2*5)+(1*3)=202
202 % 10 = 2
So 639852-53-2 is a valid CAS Registry Number.
