Check Digit Verification of cas no

The CAS Registry Mumber 85143-74-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,1,4 and 3 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 85143-74:
(7*8)+(6*5)+(5*1)+(4*4)+(3*3)+(2*7)+(1*4)=134
134 % 10 = 4
So 85143-74-4 is a valid CAS Registry Number.
