28070-25-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 28070-25-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,0,7 and 0 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 28070-25:
(7*2)+(6*8)+(5*0)+(4*7)+(3*0)+(2*2)+(1*5)=99
99 % 10 = 9
So 28070-25-9 is a valid CAS Registry Number.
