174858-25-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 174858-25-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,4,8,5 and 8 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 174858-25:
(8*1)+(7*7)+(6*4)+(5*8)+(4*5)+(3*8)+(2*2)+(1*5)=174
174 % 10 = 4
So 174858-25-4 is a valid CAS Registry Number.
