Check Digit Verification of cas no

The CAS Registry Mumber 21402-58-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,4,0 and 2 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 21402-58:
(7*2)+(6*1)+(5*4)+(4*0)+(3*2)+(2*5)+(1*8)=64
64 % 10 = 4
So 21402-58-4 is a valid CAS Registry Number.
