Check Digit Verification of cas no

The CAS Registry Mumber 900877-65-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,0,8,7 and 7 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 900877-65:
(8*9)+(7*0)+(6*0)+(5*8)+(4*7)+(3*7)+(2*6)+(1*5)=178
178 % 10 = 8
So 900877-65-8 is a valid CAS Registry Number.
