Check Digit Verification of cas no

The CAS Registry Mumber 3561-17-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,5,6 and 1 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 3561-17:
(6*3)+(5*5)+(4*6)+(3*1)+(2*1)+(1*7)=79
79 % 10 = 9
So 3561-17-9 is a valid CAS Registry Number.
