116531-51-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 116531-51-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,5,3 and 1 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 116531-51:
(8*1)+(7*1)+(6*6)+(5*5)+(4*3)+(3*1)+(2*5)+(1*1)=102
102 % 10 = 2
So 116531-51-2 is a valid CAS Registry Number.
