Check Digit Verification of cas no

The CAS Registry Mumber 5690-17-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,6,9 and 0 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 5690-17:
(6*5)+(5*6)+(4*9)+(3*0)+(2*1)+(1*7)=105
105 % 10 = 5
So 5690-17-5 is a valid CAS Registry Number.
