Check Digit Verification of cas no
The CAS Registry Mumber 549503-58-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,4,9,5,0 and 3 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 549503-58:
(8*5)+(7*4)+(6*9)+(5*5)+(4*0)+(3*3)+(2*5)+(1*8)=174
174 % 10 = 4
So 549503-58-4 is a valid CAS Registry Number.
