Check Digit Verification of cas no

The CAS Registry Mumber 58007-97-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,8,0,0 and 7 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 58007-97:
(7*5)+(6*8)+(5*0)+(4*0)+(3*7)+(2*9)+(1*7)=129
129 % 10 = 9
So 58007-97-9 is a valid CAS Registry Number.
