Check Digit Verification of cas no

The CAS Registry Mumber 121819-66-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,8,1 and 9 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 121819-66:
(8*1)+(7*2)+(6*1)+(5*8)+(4*1)+(3*9)+(2*6)+(1*6)=117
117 % 10 = 7
So 121819-66-7 is a valid CAS Registry Number.
