Check Digit Verification of cas no

The CAS Registry Mumber 31872-57-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,8,7 and 2 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 31872-57:
(7*3)+(6*1)+(5*8)+(4*7)+(3*2)+(2*5)+(1*7)=118
118 % 10 = 8
So 31872-57-8 is a valid CAS Registry Number.
