Check Digit Verification of cas no

The CAS Registry Mumber 1641-03-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,4 and 1 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1641-03:
(6*1)+(5*6)+(4*4)+(3*1)+(2*0)+(1*3)=58
58 % 10 = 8
So 1641-03-8 is a valid CAS Registry Number.
