Check Digit Verification of cas no

The CAS Registry Mumber 77148-03-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,1,4 and 8 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 77148-03:
(7*7)+(6*7)+(5*1)+(4*4)+(3*8)+(2*0)+(1*3)=139
139 % 10 = 9
So 77148-03-9 is a valid CAS Registry Number.
