Check Digit Verification of cas no

The CAS Registry Mumber 221357-57-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,1,3,5 and 7 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 221357-57:
(8*2)+(7*2)+(6*1)+(5*3)+(4*5)+(3*7)+(2*5)+(1*7)=109
109 % 10 = 9
So 221357-57-9 is a valid CAS Registry Number.
