Check Digit Verification of cas no

The CAS Registry Mumber 21091-21-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,0,9 and 1 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 21091-21:
(7*2)+(6*1)+(5*0)+(4*9)+(3*1)+(2*2)+(1*1)=64
64 % 10 = 4
So 21091-21-4 is a valid CAS Registry Number.
