Check Digit Verification of cas no

The CAS Registry Mumber 6994-98-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,9,9 and 4 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 6994-98:
(6*6)+(5*9)+(4*9)+(3*4)+(2*9)+(1*8)=155
155 % 10 = 5
So 6994-98-5 is a valid CAS Registry Number.
