Check Digit Verification of cas no

The CAS Registry Mumber 77250-80-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,2,5 and 0 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 77250-80:
(7*7)+(6*7)+(5*2)+(4*5)+(3*0)+(2*8)+(1*0)=137
137 % 10 = 7
So 77250-80-7 is a valid CAS Registry Number.
