Check Digit Verification of cas no

The CAS Registry Mumber 172748-67-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,2,7,4 and 8 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 172748-67:
(8*1)+(7*7)+(6*2)+(5*7)+(4*4)+(3*8)+(2*6)+(1*7)=163
163 % 10 = 3
So 172748-67-3 is a valid CAS Registry Number.
