98011-28-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 98011-28-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,0,1 and 1 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 98011-28:
(7*9)+(6*8)+(5*0)+(4*1)+(3*1)+(2*2)+(1*8)=130
130 % 10 = 0
So 98011-28-0 is a valid CAS Registry Number.
