87259-91-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 87259-91-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,2,5 and 9 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 87259-91:
(7*8)+(6*7)+(5*2)+(4*5)+(3*9)+(2*9)+(1*1)=174
174 % 10 = 4
So 87259-91-4 is a valid CAS Registry Number.
