Check Digit Verification of cas no

The CAS Registry Mumber 83013-75-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,0,1 and 3 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 83013-75:
(7*8)+(6*3)+(5*0)+(4*1)+(3*3)+(2*7)+(1*5)=106
106 % 10 = 6
So 83013-75-6 is a valid CAS Registry Number.
