Check Digit Verification of cas no

The CAS Registry Mumber 83399-63-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,3,9 and 9 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 83399-63:
(7*8)+(6*3)+(5*3)+(4*9)+(3*9)+(2*6)+(1*3)=167
167 % 10 = 7
So 83399-63-7 is a valid CAS Registry Number.
