Check Digit Verification of cas no

The CAS Registry Mumber 1600520-07-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,0,0,5,2 and 0 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1600520-07:
(9*1)+(8*6)+(7*0)+(6*0)+(5*5)+(4*2)+(3*0)+(2*0)+(1*7)=97
97 % 10 = 7
So 1600520-07-7 is a valid CAS Registry Number.
