Check Digit Verification of cas no

The CAS Registry Mumber 21286-57-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,2,8 and 6 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 21286-57:
(7*2)+(6*1)+(5*2)+(4*8)+(3*6)+(2*5)+(1*7)=97
97 % 10 = 7
So 21286-57-7 is a valid CAS Registry Number.
