Check Digit Verification of cas no

The CAS Registry Mumber 34021-58-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,0,2 and 1 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 34021-58:
(7*3)+(6*4)+(5*0)+(4*2)+(3*1)+(2*5)+(1*8)=74
74 % 10 = 4
So 34021-58-4 is a valid CAS Registry Number.
