Check Digit Verification of cas no

The CAS Registry Mumber 6358-41-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,3,5 and 8 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 6358-41:
(6*6)+(5*3)+(4*5)+(3*8)+(2*4)+(1*1)=104
104 % 10 = 4
So 6358-41-4 is a valid CAS Registry Number.
