Check Digit Verification of cas no

The CAS Registry Mumber 213265-81-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,3,2,6 and 5 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 213265-81:
(8*2)+(7*1)+(6*3)+(5*2)+(4*6)+(3*5)+(2*8)+(1*1)=107
107 % 10 = 7
So 213265-81-7 is a valid CAS Registry Number.
