28248-88-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 28248-88-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,2,4 and 8 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 28248-88:
(7*2)+(6*8)+(5*2)+(4*4)+(3*8)+(2*8)+(1*8)=136
136 % 10 = 6
So 28248-88-6 is a valid CAS Registry Number.
