Check Digit Verification of cas no

The CAS Registry Mumber 91021-04-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,0,2 and 1 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 91021-04:
(7*9)+(6*1)+(5*0)+(4*2)+(3*1)+(2*0)+(1*4)=84
84 % 10 = 4
So 91021-04-4 is a valid CAS Registry Number.
