528-10-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 528-10-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,2 and 8 respectively; the second part has 2 digits, 1 and 0 respectively.Calculate Digit Verification of CAS Registry Number 528-10:
(5*5)+(4*2)+(3*8)+(2*1)+(1*0)=59
59 % 10 = 9
So 528-10-9 is a valid CAS Registry Number.
