Check Digit Verification of cas no

The CAS Registry Mumber 54647-08-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,6,4 and 7 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 54647-08:
(7*5)+(6*4)+(5*6)+(4*4)+(3*7)+(2*0)+(1*8)=134
134 % 10 = 4
So 54647-08-4 is a valid CAS Registry Number.
