Check Digit Verification of cas no

The CAS Registry Mumber 67916-05-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,9,1 and 6 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 67916-05:
(7*6)+(6*7)+(5*9)+(4*1)+(3*6)+(2*0)+(1*5)=156
156 % 10 = 6
So 67916-05-6 is a valid CAS Registry Number.
