Check Digit Verification of cas no

The CAS Registry Mumber 97035-59-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,0,3 and 5 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 97035-59:
(7*9)+(6*7)+(5*0)+(4*3)+(3*5)+(2*5)+(1*9)=151
151 % 10 = 1
So 97035-59-1 is a valid CAS Registry Number.
