Check Digit Verification of cas no

The CAS Registry Mumber 4775-55-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,7 and 5 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4775-55:
(6*4)+(5*7)+(4*7)+(3*5)+(2*5)+(1*5)=117
117 % 10 = 7
So 4775-55-7 is a valid CAS Registry Number.
