Check Digit Verification of cas no

The CAS Registry Mumber 132891-57-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,8,9 and 1 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 132891-57:
(8*1)+(7*3)+(6*2)+(5*8)+(4*9)+(3*1)+(2*5)+(1*7)=137
137 % 10 = 7
So 132891-57-7 is a valid CAS Registry Number.
