Check Digit Verification of cas no

The CAS Registry Mumber 939808-69-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,3,9,8,0 and 8 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 939808-69:
(8*9)+(7*3)+(6*9)+(5*8)+(4*0)+(3*8)+(2*6)+(1*9)=232
232 % 10 = 2
So 939808-69-2 is a valid CAS Registry Number.
