Check Digit Verification of cas no

The CAS Registry Mumber 870893-92-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,0,8,9 and 3 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 870893-92:
(8*8)+(7*7)+(6*0)+(5*8)+(4*9)+(3*3)+(2*9)+(1*2)=218
218 % 10 = 8
So 870893-92-8 is a valid CAS Registry Number.
