Check Digit Verification of cas no

The CAS Registry Mumber 4290-98-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,9 and 0 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 4290-98:
(6*4)+(5*2)+(4*9)+(3*0)+(2*9)+(1*8)=96
96 % 10 = 6
So 4290-98-6 is a valid CAS Registry Number.
