Check Digit Verification of cas no

The CAS Registry Mumber 50-74-8 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 5 and 0 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 50-74:
(4*5)+(3*0)+(2*7)+(1*4)=38
38 % 10 = 8
So 50-74-8 is a valid CAS Registry Number.
