Check Digit Verification of cas no

The CAS Registry Mumber 16143-79-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,1,4 and 3 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 16143-79:
(7*1)+(6*6)+(5*1)+(4*4)+(3*3)+(2*7)+(1*9)=96
96 % 10 = 6
So 16143-79-6 is a valid CAS Registry Number.
