Check Digit Verification of cas no

The CAS Registry Mumber 181270-98-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,1,2,7 and 0 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 181270-98:
(8*1)+(7*8)+(6*1)+(5*2)+(4*7)+(3*0)+(2*9)+(1*8)=134
134 % 10 = 4
So 181270-98-4 is a valid CAS Registry Number.
