25888-16-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 25888-16-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,8,8 and 8 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 25888-16:
(7*2)+(6*5)+(5*8)+(4*8)+(3*8)+(2*1)+(1*6)=148
148 % 10 = 8
So 25888-16-8 is a valid CAS Registry Number.
