Check Digit Verification of cas no

The CAS Registry Mumber 127142-98-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,1,4 and 2 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 127142-98:
(8*1)+(7*2)+(6*7)+(5*1)+(4*4)+(3*2)+(2*9)+(1*8)=117
117 % 10 = 7
So 127142-98-7 is a valid CAS Registry Number.
