116513-25-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 116513-25-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,5,1 and 3 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 116513-25:
(8*1)+(7*1)+(6*6)+(5*5)+(4*1)+(3*3)+(2*2)+(1*5)=98
98 % 10 = 8
So 116513-25-8 is a valid CAS Registry Number.
