Check Digit Verification of cas no

The CAS Registry Mumber 21901-43-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,9,0 and 1 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 21901-43:
(7*2)+(6*1)+(5*9)+(4*0)+(3*1)+(2*4)+(1*3)=79
79 % 10 = 9
So 21901-43-9 is a valid CAS Registry Number.
