Check Digit Verification of cas no

The CAS Registry Mumber 72245-47-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,2,4 and 5 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 72245-47:
(7*7)+(6*2)+(5*2)+(4*4)+(3*5)+(2*4)+(1*7)=117
117 % 10 = 7
So 72245-47-7 is a valid CAS Registry Number.
