14898-20-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 14898-20-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,8,9 and 8 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 14898-20:
(7*1)+(6*4)+(5*8)+(4*9)+(3*8)+(2*2)+(1*0)=135
135 % 10 = 5
So 14898-20-5 is a valid CAS Registry Number.
