Check Digit Verification of cas no

The CAS Registry Mumber 4998-23-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,9 and 8 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 4998-23:
(6*4)+(5*9)+(4*9)+(3*8)+(2*2)+(1*3)=136
136 % 10 = 6
So 4998-23-6 is a valid CAS Registry Number.
