Check Digit Verification of cas no

The CAS Registry Mumber 18237-57-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,2,3 and 7 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 18237-57:
(7*1)+(6*8)+(5*2)+(4*3)+(3*7)+(2*5)+(1*7)=115
115 % 10 = 5
So 18237-57-5 is a valid CAS Registry Number.
