Check Digit Verification of cas no

The CAS Registry Mumber 74432-30-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,4,3 and 2 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 74432-30:
(7*7)+(6*4)+(5*4)+(4*3)+(3*2)+(2*3)+(1*0)=117
117 % 10 = 7
So 74432-30-7 is a valid CAS Registry Number.
