Check Digit Verification of cas no

The CAS Registry Mumber 21890-20-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,8,9 and 0 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 21890-20:
(7*2)+(6*1)+(5*8)+(4*9)+(3*0)+(2*2)+(1*0)=100
100 % 10 = 0
So 21890-20-0 is a valid CAS Registry Number.
