Check Digit Verification of cas no

The CAS Registry Mumber 74897-57-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,8,9 and 7 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 74897-57:
(7*7)+(6*4)+(5*8)+(4*9)+(3*7)+(2*5)+(1*7)=187
187 % 10 = 7
So 74897-57-7 is a valid CAS Registry Number.
