Check Digit Verification of cas no

The CAS Registry Mumber 281667-49-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,1,6,6 and 7 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 281667-49:
(8*2)+(7*8)+(6*1)+(5*6)+(4*6)+(3*7)+(2*4)+(1*9)=170
170 % 10 = 0
So 281667-49-0 is a valid CAS Registry Number.
