Check Digit Verification of cas no

The CAS Registry Mumber 78925-50-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,9,2 and 5 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 78925-50:
(7*7)+(6*8)+(5*9)+(4*2)+(3*5)+(2*5)+(1*0)=175
175 % 10 = 5
So 78925-50-5 is a valid CAS Registry Number.
