Check Digit Verification of cas no

The CAS Registry Mumber 332158-58-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,2,1,5 and 8 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 332158-58:
(8*3)+(7*3)+(6*2)+(5*1)+(4*5)+(3*8)+(2*5)+(1*8)=124
124 % 10 = 4
So 332158-58-4 is a valid CAS Registry Number.
