Check Digit Verification of cas no

The CAS Registry Mumber 3271-26-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,2,7 and 1 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 3271-26:
(6*3)+(5*2)+(4*7)+(3*1)+(2*2)+(1*6)=69
69 % 10 = 9
So 3271-26-9 is a valid CAS Registry Number.
