Check Digit Verification of cas no

The CAS Registry Mumber 897671-78-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,7,6,7 and 1 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 897671-78:
(8*8)+(7*9)+(6*7)+(5*6)+(4*7)+(3*1)+(2*7)+(1*8)=252
252 % 10 = 2
So 897671-78-2 is a valid CAS Registry Number.
