Check Digit Verification of cas no

The CAS Registry Mumber 98856-62-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,8,5 and 6 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 98856-62:
(7*9)+(6*8)+(5*8)+(4*5)+(3*6)+(2*6)+(1*2)=203
203 % 10 = 3
So 98856-62-3 is a valid CAS Registry Number.
