Check Digit Verification of cas no

The CAS Registry Mumber 3448-56-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,4,4 and 8 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 3448-56:
(6*3)+(5*4)+(4*4)+(3*8)+(2*5)+(1*6)=94
94 % 10 = 4
So 3448-56-4 is a valid CAS Registry Number.
