Check Digit Verification of cas no

The CAS Registry Mumber 61416-56-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,4,1 and 6 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 61416-56:
(7*6)+(6*1)+(5*4)+(4*1)+(3*6)+(2*5)+(1*6)=106
106 % 10 = 6
So 61416-56-6 is a valid CAS Registry Number.
