Check Digit Verification of cas no

The CAS Registry Mumber 74178-21-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,1,7 and 8 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 74178-21:
(7*7)+(6*4)+(5*1)+(4*7)+(3*8)+(2*2)+(1*1)=135
135 % 10 = 5
So 74178-21-5 is a valid CAS Registry Number.
