87544-20-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 87544-20-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,5,4 and 4 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 87544-20:
(7*8)+(6*7)+(5*5)+(4*4)+(3*4)+(2*2)+(1*0)=155
155 % 10 = 5
So 87544-20-5 is a valid CAS Registry Number.
