Check Digit Verification of cas no

The CAS Registry Mumber 81820-57-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,8,2 and 0 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 81820-57:
(7*8)+(6*1)+(5*8)+(4*2)+(3*0)+(2*5)+(1*7)=127
127 % 10 = 7
So 81820-57-7 is a valid CAS Registry Number.
