Check Digit Verification of cas no

The CAS Registry Mumber 3149-08-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,1,4 and 9 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 3149-08:
(6*3)+(5*1)+(4*4)+(3*9)+(2*0)+(1*8)=74
74 % 10 = 4
So 3149-08-4 is a valid CAS Registry Number.
